Richard Kerekes

Dr. Kerekes is Professor Emeritus from the University of British Columbia. His career in the paper industry spans more than 40 years. Through his research, he has contributed to the development of new technology in the areas of fiber processing and papermaking.
Richard was born on July 9, 1940 in Welland, Ontario to Joseph and Elizabeth Kerekes.
Kerekes received a B.A.Sc. (1963) and a M.A.Sc. (1965) in Mechanical Engineering from the University of Toronto. In 1970 he earned a Ph.D. in Chemical Engineering from McGill University (Montreal).

Shortly after earning his Ph.D., Dr. Kerekes joined PAPRICAN and was based in Pointe Claire, Quebec. In 1978 he moved to British Columbia where he helped to establish PAPRICAN in western Canada and led the creation of the Pulp and Paper Centre at UBC.

Kerekes’ vigorous research program led to breakthroughs in understanding numerous operations in papermaking, including pulp mixing, refining, forming, pulp screening, pressing, and calendering. Among these accomplishments was pioneering work on the hydrodynamics of blade twin-wire formers. Application of his body of research has enabled substantial improvements to both fiber and paper quality.

His fundamental research on fiber suspensions led to the formulation of the Crowding Number, a dimensionless number important in understanding the flocculation tendencies of pulp, as well as the behavior of fibrous networks.

Kerekes is the author or co-author of over 120 technical papers and a Fellow of the following technical associations: The Chemical Institute of Canada, TAPPI, The Canadian Academy of Engineering, the International Academy of Wood Science, and PAPTAC. He has received numerous honors and awards including: the John S. Bates Gold Medal of PAPTAC, the TAPPI R&D Award and W.H. Aiken Prize, the Johannes Van den Akker Prize (in 2007 and 2009), and the TAPPI Gunnar Nicholson Gold Medal.

Richard and his wife Valerie celebrated 40 years of marriage in 2018. They have one son, Joseph.

Luigi Lazzareschi

Luigi Lazzareschi was born on February 13, 1963 in Pescia, Italy, an area with a long tradition of paper production. His father, Giuseppe, partnered with Emi Stefani in 1966 to start a papermaking business. This laid the foundation for what is today known as the Sofidel group, a company that, under the leadership of Luigi Lazzareschi, has grown to be the sixth largest tissue-producer globally.

Mr. Lazzareschi joined Sofidel in 1987 and became Head of Marketing in 1988. In his more than 30 years with Sofidel, and as current CEO of the Sofidel group, Mr. Lazzareschi led expansion from a small, Italian company to a multi-national corporation with 18 companies throughout Europe and the United States. By 2017, total production exceeded one million tonnes of paper, and the company employed more than 6,000 people.

Driven by a strategy prioritizing innovation, service to mass retail, and advertising as keys to growth of market share, he enabled the company to move away from strictly price-oriented competition. This approach led to the rise of Regina; Sofidel’s most well-known brand.

Under Lazzareschi’s leadership, Sofidel placed strategic importance on environmentally responsible growth; emphasizing industry-leading sustainability targets related to CO2 emissions, water consumption and raw material sourcing.

Mr. Lazzareschi has been recognized for his leadership with various awards including: Knight of the Italian Republic, Commander of the Italian Republic, Ernst & Young Entrepreneur of the Year Award, and the Transatlantic Award from the American Chamber of Commerce in Italy.
Mr. Lazzareschi and his wife, Maria Pia Del Perugia reside in Coselli, Italy.

Lisa Viikari

Dr. Liisa Viikari was born in Helsinki, Finland on 30 January, 1949.

Dr. Viikari served as a professor from 1995 until her retirement in 2013, first at VTT and since 2007 at the University of Helsinki. Prior to receiving a Doctor of Technology degree in 1986, she earned a Master of Science in Biochemical Engineering, and a Licentiate in Biotechnology. Dr. Viikari is also a Docent in Biochemical Process Technology.

Dr. Viikari is both a scientist and an educator. She is the author or co-author of over 450 publications, including about 200 peer-reviewed articles and book chapters. Additionally, she has authored or co-authored over 30 patents and patent applications. By 2008, Dr. Viikari had more patents to her name than any other Finnish woman.

Her research focus on industrial biotechnology; especially on the development and use of enzymes in converting wood and agricultural residues into useful products has had substantial impact on the pulp and paper industry. Her work with hemicellulolytic enzymes enabled the reduction of chlorine-based bleaching. In addition to positive environmental impact, the technology actually enabled a brightness improvement. This work was a critical development, paving the way for Elementally-Chlorine Free (ECF) and Totally Chlorine Free (TCF) bleaching processes. Later work focused on the use of enzymes for biorefining, and enzymatic modification of lignin to produce useful chemicals capable of replacing oil-based products. Most of her R&D activities were carried out in close collaboration with industry. Many of Dr. Viikari’s contributions represent important process innovations for the pulp and paper industry; additionally, much of her work has shown the potential for a forest-based biorefining industry.

Dr. Viikari has been honored with the following awards: the VTT Prize for Scientific Excellence, The Emmanuel Merck Award, the Anselm Payen Award, the Award of the Ministry of the Environment, the Walter Ahlstrom Award, Knight First Class of the Order of the White Rose of Finland, the Charles D. Scott Award, and the Linnebon Prize.

Dr. Viikari and her husband, Timo, have three children.

Heikki Peltola

Heikki Peltola was born in Asikkala, Finland on May 14, 1943.

Mr. Peltola graduated from the University of Helsinki in 1969 with a Master of Science degree. After beginning his career at Enzo-Gutzeit, he joined United Paper Mills Corporation (UPM) in 1971 as a production engineer. After an exemplary career with UPM spanning nearly four decades, he retired in 2005 as Senior Vice President of Technology.

In the 1970s and 1980s, UPM saw rapid growth and expansion in manufacturing of wood-containing printing papers. Mr. Peltola managed the construction and start-up of multiple of these new lines. Judicious risk-taking and some key development partnerships enabled successful incorporation of new technologies into full-scale production assets for the first time. Some of these technologies were: mechanical pulping (TMP), twin-wire forming, high-speed electric drives, wider machines, and on-machine blade coating. These bold moves put UPM in a strong competitive position when other companies were faltering. This strength enabled UPM to expand through acquisition and merger into UPM-Kymmene, the forest-based bio industry giant that it is today. Mr. Peltola’s technical leadership and wise project management was critical to the success of the company and to the advancement of many technologies important to the paper industry.

Mr. Peltola served in numerous project management and technology roles at various UPM mills throughout Europe and beyond, including as Technology Supervisor at a UPM joint venture in China and Singapore. In 2001, he was named Senior Vice President of Technology.

In 2005, Mr. Peltola and his wife retired to a life in the country on their forest farm in Finland.

Douglas Wahren

Douglas Wahren was born in Norrköping, Sweden on March 12, 1934. He received his Masters (1956) and Ph.D. (1964) in Mechanical Engineering, both from the Royal Institute of Technology, Stockholm, Sweden.

After graduation, he worked with many prestigious institutions including Beloit Corporation, U.S.A (1964); STFI, Stockholm, Sweden (1969-73); AB Karlstad Mekaniska and Werkstad, (KMW), Sweden (1974-79); Institute of Paper Chemistry, Appleton, Wisconsin, U.S.A (1979-87); STORA Tech., Sweden1987-96); and in 1996 founded his own consulting firm “The Profit Professor” (1996). Douglas Wahren was a man full of ideas. 

Wahren’s excellent work on three-dimensional fiber networks has led to the development of modern hydraulic paper machine head boxes. His research has led to a greater understanding of sheet formation from “fiber dispersion” to “Floc dispersion” and has been the basis for many subsequent wet-end innovations such as high consistency forming. 

Wahren’s research has led to other notable achievements such IMPULSE DRYING (1970), a process involving more intense drying rather than trying to further the size of the dryer section. STFI’s Impulse technology program was inaugurated by the King of Sweden, Carl XVI Gustaf with Wahren as the guest of honor. 

Wahren’s SSVL Project report with James Davis (1981) is an excellent resource for the closed paper mill concept for saving energy and water. Wahren holds seventeen (17) patents, and has published three (3) books and at least fourteen technical papers. In recognition of his significant achievements, he was awarded the TAPPI Gunderson Nicholson Gold Medal (1998), TAPPI Research & development Research Div. Award and William H. Aiken Prize (1990); TAPPI and Board Mfg. Div. Award and Harris O. Ware Prize (1988); Swedish Royal Academy of Engineering Science Award (1987); TAPPI Fellow (1981) and the Honorary title of professor at Stockholm’s Royal Institute of Technology (1973). He married his childhood friend, Inger, in 1957.

Wahren caught polio in 1949 at the age of fifteen, was unconscious for six weeks and found himself paralyzed from the neck down. His treatment with penicillin, strenuous physical therapy, positive outlook and sheer determination helped him get better. He was a member of TAPPI Paper Physics Committee and Sigma Xi.

Wahren died on December 27, 2011 in Täby, Sweden where his wife still resides. He had two children: Daughter Caroline who lives in Täby; Son lives in Waterville, Ohio, U.S.A.

Averill John Wiley

Averill Wiley was born in Pullman, Washington, on June 10, 1911. After attending Whitworth University for two years, he received his Bachelors (1935) and Masters (1936) of Science degrees, both from the Washington State University and subsequently did graduate work for 2.5 years at the University of Wisconsin, Madison. Averill was an early environmental scientist who specialized in the development of alternative uses of the spent products from the pulp and paper industry. 

Following a short stint as a bacteriologist for the city of Spokane, Washington, he was hired as the Technical Director of the Wisconsin Sulphite Pulp Manufacturers Research League (SPMRL) to operate and manage a small pilot plant in Appleton, Wisconsin. By 1966, SPMRL grew to include 38 U.S. and 3 Canadian pulp mills, a laboratory and the pilot plant. The staff grew to include 56 chemists, technicians and administrators. The SPMRL was later renamed as Pulp Manufacturers Research League (PMRL) that eventually merged with the Institute of Paper Chemistry, Appleton, Wisconsin. (late 1970s).

Many productive and environmentally significant uses of sulphite pulp wastes were developed under Wiley’s direction. He was one of the first to make use of reverse osmosis technology for cleaning up effluents from sulphite mills. He later conceptualized that it takes less energy to freeze water than to evaporate it and combined reverse osmosis technology with a freeze-concentration step that reduced energy costs for the overall process. It was a highly successful pilot-plant demonstration at two pulp mill locations.

Wiley was the author, or co-author, of 65 technical papers, one book and seven (7) U.S. and foreign patents. 

Wiley was awarded an honorary Doctor of Laws degree from Gaulladet College in Washington, D.C. “for a distinguished career as a bacteriologist, biochemist, and research director (1968); Invited to present a research paper at the International TAPPI Conference in Stockholm, Sweden (1953); He was chosen out of 700 candidates and awarded the Nash Prize for Conservation for his “Outstanding Contribution in Reducing Sulphite Stream Pollution (1950).

He was a member of the American Chemical Society, Technical Association of the Pulp and Paper Industry and the Alexander Graham Bell Society. He received the Nash Award for Conservation for his “outstanding contributions in reducing sulphite stream pollution”. Wiley accomplished all of this even though he had lost his hearing at the age of 15 due to meningitis

Averill Wiley died in Appleton in 2002 at the age of 91. His wife, Maud, died in 2013. They have two sons, Averill J. Wiley Jr. and William T. Wiley.

Thomas A. Gardner

Thomas Gardner was born in Green Bay, Wisconsin on June 8, 1926, the first born son of Alfred T Gardner, papermaker at Combined Locks Paper company. The family moved from Appleton to Port Arthur, Ontario in 1941 where Tom attended Port Arthur Collegiate for two years. Prior to completing high school in Duluth, he served one season on the Great Lakes cruise ship, SS Noronic, and a second season on ore carriers. He then served in the Canadian Navy in the North Atlantic in 1944-45. Gardner received his B.S. in Mechanical Engineering from Oregon State University, Corvallis, Oregon in 1949.

Following graduation, Gardner worked for Abitibi Power and Paper in Ontario, Canada as a design engineer (1949-53); for Marathon Corporation (American Can) in Neenah, Wisconsin as senior staff engineer (1953-64); and then worked with Overly Inc., Neenah, Wisconsin, where he designed and built Gardner High Velocity Dryers and floater dryers (1964-74). He later licensed Valmet-Enerdry, Thunder Bay, Ontario, and Knoxville, Tennessee, to build and install Gardner pocket ventilation systems (1971-90). As President and CEO of Gardner Systems Corporation, Neenah, Wisconsin, he developed and produced Gardner Blow-Through Steam Control Systems (1990-2011).

While working at Marathon, Gardner developed and patented his ideas of applying air jets at high velocity to produce high rates of heat and mass transfer for drying webs, and in 1958 successfully installed the first on-machine coater equipped with a Gardner Dryer.

Gardner dryers found use in a variety of applications worldwide such as drying coatings on paper machine coaters, on high speed off-machine coater installations, on Yankee tissue machines, and for drying of heat-set inks. He also invented and patented the high velocity “Floater” dryer that dried heat-set inks on both sides of the web at up to four times previous speeds.

He then developed and patented the Pocket Ventilating system that provided uniform drying across the web in paper machine dryers.

At Gardner Systems he went on to develop the new Gardner-Blow-Through Steam Control System for supplying steam and condensate drainage at high efficiency from paper machine dryers including the latest high speed dryers. Over 150 of these systems have been installed on paper machines around the world.

Gardner has 5 US Patents and 26 Technical Publications to his credit. He was a licensed Professional Engineer of the Province of Ontario and of the State of Wisconsin; a member of the Technical Association of Pulp and Paper Industry (TAPPI); the Canadian Pulp and Paper Association (CPPA); the Paper Industry Management Association (PIMA); the Graphic Arts Technical Foundation’s Technical Advisory Committee (GATF); the International Association of Scientific Papermakers (IASPM); and Pi Mu Epsilon – Mathematics Honor Society. He also received many Certificates of Appreciation for his numerous consulting services to the paper industry.

Gardner attributes much of his success to the support of his father, Alfred Gardner, as well as many other great paper industry people including Justin Jordan, manager of Abitibi’s mill at Port Arthur and president of CPPA, John Osborne, chief engineer at Bowaters Southern Paper Corp. and president of TAPPI, and Bill Overly, owner of Overly, Inc. (all now deceased).

Throughout his life Tom enjoyed many activities including scuba diving, sailing, alpine skiing, hunting and playing the piano.

Thomas Gardner retired in 2011 and lives in Neenah, Wisconsin. His wife for 60 years, Dorothy, passed away in 2006. They have four sons and two daughters.

Niilo Hakkarainen

Niilo Hakkarainen was born in Isalmi, Finland on December 22, 1927 and received his diploma engineer (M.S.) degree with a major in Paper Technology from the Helsinki Technical University in 1953. 

After graduation, Hakkarainen worked for Oy Papyrus Ab as a sales engineer (1953 – 54); with Oy Keskuslaboratorio Ab (KCL) as a research engineer (1954 – 55). This was followed by 12 years of employment with Kemi-Oy, first as a production manager (1955 – 58 & 1960 – 62) and then as director of pulp and paper (1962 – 66) rising to the position of CEO (1966 – 69). In 1970 he was invited to follow Juuso Walden (Hall of Fame Inductee) as President and CEO of United Paper Mills (UPM).

Hakkarainen was a visionary leader but a controversial person. He invested in the breaking field area of Thermo-Mechanical Pulp (TMP) manufacturing technology for products such as newsprint and both coated and uncoated magazine grades. The TMP process came from UPM’s Engineering Division Jylhävaara, the talc from UPM’s own mine and much of the twin wire paper machine development was done in partnership with Valmet.

Under Hakkarainen’s leadership of nearly 20 years (1970 – 1990), he turned UPM around to become one of the top paper companies of Finland through cost cutting and innovation. During his tenure, UPM experienced phenomenal growth and built eight world class paper machines, three of them in green field locations in the UK and France. Out of the eight, seven machines produced printing grades and the largest produced release base paper line.

Other key developments included pressure sensitive label laminations, air laid papers, composite materials with paper, polymers and aluminum foil and an aseptic liquid packaging system. Of these, the label laminates grew to a world-class business. At the end of Hakkarainen’s era in 1991, UPM was not only Finland’s strongest pulp and paper company, but also one of the world’s largest. 

Hakkarainen was a member and Chairman of the board of Sales Association Converta (1971 – 88); member of the board, Daily Mail and General Trust (1990); and a member of the Finnish Paper Engineer’s Association. 

The honors he received included the Finnish Paper Engineer’s Association (FPEA) Lampen Medal (highest honor FPEA bestows to any member) and the C.J. Jansson Prize. Interestingly, he refused to receive the highest honorary title in business, the Vuorineuvos title (Bergsrad in Swedish), because it was going to cost his company money!

Niilo Hakkarainen died in Helsinki, Finland on July 18, 2011. He is survived by his wife Kristiina who lives in Helsinki. They have three children – Nina, Eva and Anna.

Juhani Strömberg

Juhani Strömberg was born in Pori, Finland on September 11, 1941. He received his M.S. degree in Radio Chemistry from the University of Helsinki, Finland in 1968.

Strömberg worked with the University of Helsinki in the Department of Radio Chemistry (1969 – 82); United Paper Mills Ltd. (UPM), Tampere as General Manager of Label Materials (1982 – 85); UPM-Kymmene Corporation as President of Raflatac Group (1985 – 2002) and later became Senior Vice President, R & D, Raflatac Group (2002 – 03). 

Strömberg conceived of and spearheaded the water-based label stock laminates, the development of which revolutionized the global market. Label stock is important to the paper industry because the final product needs both face and release papers. In 1969 Strömberg was named product development manager in Raf. Haarla, later Raflatac, a division of UPM. He soon realized that water-based label stock laminates would have great opportunities because of qualitative and environmental reasons. But the costs were high due to the off-line manufacturing. Strömberg successfully developed and implemented the on-line manufacturing process, a procedure that had not been accomplished by any of the competitors. 

Strömberg’s team mastered a three-fold innovation: solid water-based adhesives, solvent-free silicones and advanced on-line production. The ability to do this at high speeds took 10 years to develop. During those ten years Strömberg’s team never lost faith. Turnover increased quickly by forty-fold from 1976 – 80 and rose another six times from 1980 – 85. The innovations of Raflatac have been a good example and motivator for further innovations in the converting industries. 

Strömberg led the development of a superior glassine released paper and influenced the development of better-quality face papers. The developments revolutionized the global market; their market share rose from 3% in 1970 to 65% by the end of the 1980’s.

Strömberg also made use of information technology to develop internal internet and real time customer service. Under his leadership, the delivery times for label-stock that had been weeks long were cut to a revolutionary 24/48-hour delivery, especially in the U.S.A.

Strömberg has 5 patents to his credit. He received the President of Finland’s Export Prize of the Year (1986); City of Tampere’s Technical Creativity Award (1992); President of Finland’s High Finnish Honorary Title (1999); Tampere Chamber of Commerce’s Business Leader of the Year (2000); Tampere University of Technology’s Doctor h.c. (2002) and Lampen Medal from the Finnish Paper Engineer’s Association (2012). 

Juhani Strömberg lives with his wife, Paula, in Tampere, Finland. They have two sons – Samuli and Petteri.

Irwin A. Pearl

Irwin Pearl was born in Seattle, Washington, on December 25, 1913. He received earned a Bachelor of Science in 1934, a Master of Science in 1935, and a Ph.D. in 1937, all from the University of Washington, in Seattle.

After serving in responsible technical positions (1937-40), Pearl joined the Institute of Paper Chemistry (IPC) in 1941 and worked as senior research associate and professor (1941-76) where he began his pursuit of lignin chemistry. In 1955, he was appointed leader of the Lignin Group. From 1977-90, he was a chemical consultant to the forest products industry.

Starting in 1941, Pearl recognized and explored the hidden value of lignin in black liquor—one of the first in the world to do so. He was a strong believer in the use of byproduct materials to create value-added products, and saw lignin derivatives as a rich opportunity that could rival petroleum and coal tar as a source of synthetic materials. He showed that, with further chemical treatment, lignin in kraft black liquor could yield useful lignosulfonates similar to those coming from sulfite pulping.

Pearl isolated vanillin and produced related products such as esters, amides, ethers, and other compounds from lignin that could be used for slime control, treatment of fungal infections, preservatives, and other applications. Thanks to his efforts, 1.25 million tons per year of lignin were productively diverted from streams and rivers. The work he launched was ahead of its time, and is now called biorefining.

In 1952, working with Robert Cohen, Pearl produced ethyl vanillate from lignin, providing an inexpensive source for a compound needed to treat serious, and sometimes fatal, fungal infections including actinomycosis, or lumpy jaw; histoplasmosis; blastomycosis; and coccidioidomycosis, or “Valley Fever.” Ethyl vanillate made from byproducts of wood pulp was used to treat patients in North America and Europe, as reported in The Science News-Letter and The British Medical Journal. The production of ethyl vanillate from wood pulp filled a critical need at a time when other treatments had not yet been discovered. Turning a study of lignin from black liquor into life-saving medication is an important example of the benefits that can come from research in our industry.

Pearl has over 100 publications in the Journal of the Chemical Society and other reknown journals and magazines. He was the author of The Chemistry of Lignin (New York: Marcel Dekker, 1967). His authoritative articles on lignin were published regularly in TAPPI Journal. He has 59 US patents and over 100 foreign patents to his credit.

He was an active member, later an Emeritus member, of the American Chemical Society, a Fellow of the New York Academy of Sciences, and a member of the Forest Products Research Society, TAPPI, Phytochemical Society of North America, the Wisconsin Academy of Sciences, and the American Philatelic Society. Pearl and wife Lillian were enthusiastic members of the Square Dancing Club.

Pearl passed away on May 14, 2014, in Wilmington, Delaware, at the age of 100, his wife Lillian died in 2005. They had two children; daughter Cheryl Kamm, who died in 2014, and son Hugh Pearl, who lives in Sleepy Hollow, Illinois.

Charles P. Klass

Charles (Chuck) Klass was born on February 6, 1940, at Piqua, Ohio but grew up in Dayton where his father worked. In 1962, Class received his Bachelor of Science degree (BA) from Western Michigan University, Kalamazoo, MI, and his Masters in business management (MBA) from Pace University, New York City in 1968

Klass started working before and after he received his degrees. Some examples of his jobs included working at paper schools, paper, and allied industries, in sales & marketing and at trade Journals. He ended up in the management ladder when he started Klass Associates Inc., in 1986, and led the corporation to a huge success as its President.

Klass has over five (5) decades of pulp and paper and allied industry experience including 28 years as a consultant and innovator in the field of coated paper, paperboard, tissue, and many other paper-based products to paper related businesses all over the world, especially in countries such as Australia, Brazil, Canada, China, Chile, Colombia, India, Japan, Korea, Mexico, Norway, Sweden, Turkey, UK, USA, and Uruguay.

Klass’s contributions led to the commercialization of the metered size press; coating of deinked post-consumer recycled waste papers; improving grease resistance, the development of Crayola Wonder paper, the development of rod coaters for Kohler Coating, the commercialization of nanoparticle big latex binders for Ecosynthetix, and the development of Colorlok technology for Hewlett-Packard for their inkjet papers.

Klass has 7 US and International patents to his credit. He has published 164 technical papers including chapters in books, TAPPI Journal and Nordisk Celulosa and other trade journals focusing on applied technology. The great majority of the publications appear as invited presentations in many conference proceedings worldwide.

Klass is a member of PIMA; TAPPI and CPPA. His public service activities included Jaycees, South Brunswick Township Recreation Commissioner, Lieutenant, and Pilot with New Jersey Civil Air Patrol, Board member of Philadelphia’s American Cancer Society,

For his contributions he received many honors including TAPPI Gold Medal; TAPPI Fellow; TAPPI Paper and Board Manufacturing Division Award and Harris O. Ware Prize; TAPPI Distinguished Service Award; TAPPI Coating and Graphic Arts Division Leadership and Service Award and became Western Michigan University’s Fellow. He also received the Paper Technology Foundation’s Hall of Fame Award.

Chuck Klass and his wife Beverly, live in Madeira Beach, Florida. They have one daughter and three grandchildren.

Wang Zhen

Wang Zhen was born during the Yuan Dynasty of China in 1271. He became a government official and saw a need to advance the future of agriculture in China by documenting and publishing the many technical innovations he saw throughout China with the hope of alleviating poverty by spreading that knowledge. To achieve his ambition, an effective printing method would be needed to print not just a few copies but thousands of copies of an extensive manual, not only for the workers but also for officials who could guide their people.

Wang Zhen’s book, the Nong Shu or The Book of Farming was published in 1313 and had 800 pages and 100,000 words. It was a highly illustrated agricultural bible, full of Da Vinci-like drawings that would be used throughout China to instruct farmers and facilitate knowledge transfer.

Wang Zhen’s primary innovation was a system that improved the speed and efficiency of typesetting.  It had rotary tables to help typesetters quickly sort and process thousands of carved wooden blocks for use in a printing press. This mass-produced book and the ensuing industry of printing would be part of the driving force for the growth of the paper industry internationally.

Wang Zhen explored several approaches but determined that wooden block movable type would be most effective since the many unique Chinese characters that would be needed could be quickly hand-carved. His work with wooden movable type was primarily conducted in the years 1297 or 1298.

Though not the inventor of movable type itself, he created the first mass-produced book. Its illustrations show a dizzying array of technologies such as water wheels, water-powered bellows, pumps, gears and pulleys, the blast furnace, and other inventions that were long attributed to later European inventors. Although controversial, one American author even argues that copies of the Nong Shu arriving in Italy may have inspired Da Vinci and sparked the Italian Renaissance. In any case, there is little doubt that Wang Zhen’s accomplishment should also be recognized with that of Gutenberg and other giants of innovation.

Gutenberg has been recognized as one of the greatest inventors of all time for the monumental impact he had on printing. His printed Bible has often been called the world’s first substantial mass-produced book printed with movable type. That achievement came in 1455, just 142 years after the world’s actual first mass-produced book printed with movable type by long-neglected inventor and government official, Wang Zhen.

Wang Zhen died in 1368.

Norm Dove

Norm Dove was born in Romford, Essex, England on October 29, 1941. He attended Thurrock Technical College from 1957 to 1963, where he obtained a Higher National Certificate plus endorsements. From 1957-65, he worked with Van den Burgs and Jurgen of Unilever Brothers (1957-65); with Dominion Engineering’s Paper machine division (1965); with American Can Co. as project engineer (1965-68) and then with Crestbrook Forest Industries, B.C., Canada as Sr. project Engineer (1968-77).

Dove’s legacy began in 1970 when, while working for Crestbrook, he designed a better steam shower system for a Fourdrinier that enabled a significant increase in machine speed. He obtained a patent for his invention, the first of over 33 in his name. The boost in productivity from this device would lead to his founding of Devron Engineering Ltd. in 1972 and becoming its President.

The first sale of the now famous Devronizer to Consolidated Papers in New Richmond, Quebec resulted in a 15% increase in production on a linerboard machine. His Devronizer would be applied over the Fourdrinier, the couch, and in the press section, with impressive success. But Dove’s quest for innovation did not stop there.

His company soon expanded its product line to include dry-end steam applications (Calendizer), slice lip actuators (Autoslice), calendar stack actuators (Calcoil), and coat weight actuators (ProCoat). Dove’s SuperFlex Titanium Slice Lip gave significant gains in productivity and quality by enabling much tighter basis weight control. As business grew, Dove required employees to be trained in Edward Deming’s system of statistical process control. He drove attitudes of quality and zero-failures in every aspect of their work.

In the area of cross-direction (CD) actuators and controls, Devron enjoyed a worldwide market share of 30% by 1990. Compact, automated actuator beams networked to the mill’s QCS system allowed CD variation in sheet properties to be dramatically reduced, often by over 50%. The CD actuators and controls from Dove’s work continue to benefit many of the paper machines in operation today.

In September 1991, Devron was acquired by Measurex, which in turn was acquired by Honeywell in 1997. The Devron methodology and passion for excellence continues today at Honeywell’s Center of Excellence in the original Devron factory in North Vancouver, B.C.

Norm Dove and his wife, Nan, live in Echo Valley Ranch, B.C., Canada.  Norm has three daughters, Ashlie, Megan and Amy.

Havilah Babcock

Havilah Babcock was born in Franklin, Vermont on September 8, 1837.  He attended school in Vermont and in Waukesha, Wisconsin before his family came to Neenah in 1849. There, at age twelve, he and his brothers worked for their father, a building contractor hired to construct the Neenah segment of the Fox-Wisconsin Waterway.

In 1857, while still in their teens, Babcock and his friend Alfred Kimberly started their own dry goods business. The two young men also established the unusual business culture of equal ownership and shared management. In 1869 they made use of Babcock’s construction background to build the Reliance Mill, the city’s largest flourmill.

In 1872, Kimberly and Babcock organized a joint stock paper company with four other investors. A month later the investors changed to include C. B. Clark and F. C. Shattuck and the company renamed Kimberly, Clark & Co. In 1874, by a memorandum of agreement, the equal ownership was formally established between the four partners: Kimberly, Babcock, Clark and Shattuck. In doing so they consciously avoided the dissension that plagued other businesses and experienced an unparalleled rate of growth and expansion.

Beginning with the construction of the Globe Paper Mill in 1872, the company purchased the original Neenah Paper Mill in 1874; organized the Atlas Paper Company in 1878; constructed the Vulcan Paper Mill in 1881; the Tioga Paper Mill in 1883; the Badger Paper mills in 1884; the new Neenah Paper Mill in 1885; organized the Telulah Paper Company in 1887; and constructed the Kimberly mill in 1889.  Through this rapid expansion of capacity, Kimberly, Clark & Co. established the Fox River Valley as one of the leading centers of paper production in the United States of America.

In 1880, the company was incorporated as Kimberly & Clark Co. with Kimberly as President and his closest associate Babcock, as Vice President, working together for the next twenty years. Babcock would also take a highly visible leadership role in the organization of the Shattuck & BabcockPaper Co. in 1890, which would become the largest producer of fine writing papers in the U.S.

In 1889, F.J. Sensenbrenner (1998 Hall of Fame Inductee) had joined Kimberly & Clark Co. as an accountant.  As Clark died in 1890, Shattuck in 1891 and Kimberly withdrew from work in 1905; Babcock served as a pivotal link in the transition of leadership to F. J. Sensenbrenner. In 1928 when Kimberly died and Sensenbrenner became President, the name of the company was changed for the fourth time to Kimberly-Clark Corporation.

Havilah Babcock died on April 21, 1905. He was survived by his wife and five children.

David A. Bossen

David A. Bossen was born in Clinton, Iowa on January 9, 1927. He was 12 years old when his father died and so he started working at the Clinton Post Office and at age 14 rode shotgun when they drove the bank deposits to Chicago. In 1950, he married Doris Stephens.

Bossen served in the U.S. Marine Corps (1945-46) and received a fleet appointment to the U. S. Naval Academy, Annapolis, MD (1946-49). He earned his Bachelor of Science Degree in electrical engineering from M.I.T ca. 1951. Later, he worked for Alcoa as Industrial Engineer (1948-51) then as VP & GM for Industrial Nucleonics (AccuRay) (1952-67) which was later bought by Combustion Engineering and then in turn was acquired by ABB.

In 1968, Bossen founded Measurex Corporation and was at its helm until 1997. This was a revolutionary period for the paper industry, since prior to this time few paper machines were equipped with on-line measurement sensors and control systems. The technology developed by Measurex led to improved paper quality, reduced paper losses, better machine efficiency, energy savings and optimized use of raw materials.

Bossen was so confident of his technology that he offered a “Results Guarantee” of 99% uptime operation. Hence, as the “Results Company”, Measurex grew rapidly installing over 3,000 paper machine control systems worldwide by 1988. Today, close to 100% of paper machines use on-line control systems benefitting from technologies developed by Measurex (and subsequently by others) that allow paper machines to operate efficiently.

Bossen was also an innovator and a leader. He surrounded himself with the most outstanding personnel that he could find, across a wide array of disciplines. He followed an intensely involved, hands-on management approach and treated his employees as family. This led to a company that the employees called “an amazing culture”.

Measurex was acquired by Honeywell in 1997. Bossen had served Measurex as CEO and then Chairman of the Board until 1997. He retired in 2000 as “Chairman Emeritus”. He was a TAPPI Fellow, a member of PIMA, and a member of American Electronics Association. He had 19 patents to his credits.

David Bossen died on April 21, 2015 at his home in Menlo Park, California at the age of 88. He was preceded in death by his first wife of 40 year, Doris, and his daughter Julie Ayerza. He is survived by his second wife of 24 years, Darlene, three daughters, one son, nine grandchildren and one great-grandson.

Bjarne Holmbom

Bjarne Holmbom was born in Ingå, Finland on September 28, 1943. His father was a farmer and his mother a school teacher in the village where they lived. He had two brothers, one died and the other has continued to farm.

Holmbom went to school at the age of five, which is rather unusual in Finland where the normal school starting age is 7 years. He finished high school in 1961 at the age of 17. He joined the ÅA University to study chemistry in the faculty of chemical engineering that provided education in wood chemistry and pulping technology. He earned his M.Sc. degree in 1967 and Ph.D. in 1978 and got very interested in the chemistry of wood and its application in new product development.

After his Ph.D., Holmbom continued to work at the ÅA University, first as a research scientist and later took on different teaching responsibilities and, in 1981, was appointed Professor. During this period he also visited the Pulp and Paper Research Institute of Canada (1979–1980); North Carolina State University. U.S.A. (1985–1986); and INPG- EFPG, Grenoble, France (1999). He retired from his professorial responsibilities in 2008 but continued to work as a Scientific Advisor at ÅA University. In addition, together with his son, he also ran a small family company, Separation Research Ltd., providing analytical and preparative services mainly for the forest industry.

Holmbom started his research career working on tall oil produced in the chemical pulping processes and later expanded into environmental and paper chemistry areas. His key expertise and innovations relate to the utilization of wood components as a resource for value added products. For example, he extracted lignans and other polymers, such as poly-phenols, from wood and developed their usage in medicines, in functional foods, sun creams, technical antioxidants, and as natural organic biocides.

Holmbom and his colleague, Christer Eckerman, worked on breakthrough research and innovation creating a platform for large-scale separation, isolation, purification and applications of chemical components from wood, especially knots. It is said that Holmbom’s research has made an important contribution towards making the forest products industry a biorefining industry.

Holmbom has 14 patents to his credit, has published 266 papers, and 31 book-chapters.

He received many awards and recognitions such as the Marcus Wallenberg Prize, shared with Christer Eckerman (2008); Mark of Honor presented by the President of Finland; Langen Medal FPEA (2006), Finnish Science Award by Ministry of Education (2006); and Tallus Prize for Environmental Research (1996).

Bjarne Holmbom lives with his wife, Ulla Ericke, in Åbo, Finland.

Alf de Ruvo

Alf de Ruvo was born October 28, 1938 in Sweden. After obtaining his M.Sc. in Chemistry and a Licentiate (Ph.D.) in Engineering with emphasis on paper technology, he moved to the United States where he worked as a research scientist for about 2 years.

In 1970, he accepted an appointment at the Swedish Forest Research Laboratory (STFI) where he quickly rose to become head of research in their Pulp and Paper Technology Department and worked on many projects dealing with paper physics, paper composites, converting and product properties. He was the motivating force behind a unique experimental paper machine. His greatest achievement was creating a research climate that inspired people. He was full of imagination and built a great international contact network.

Alf de Ruvo’s soul was in research. In 1983, he became Director of Research at Sunds Defibrator AB where he achieved many breakthroughs of new technologies. He was committed not only to the technical development but also to the introduction of Sund’s technologies to customers.

In 1987, he joined Svenska Cellulosa Aktiebolaget (SCA) where, in 1993, he became the executive vice-president and the head of R&D. At SCA he was the moving force behind radical renewal of the SCA’s product portfolio thereby establishing a new research culture in the company. He spearheaded a composite materials approach on paper packaging materials.  He also worked on the water absorption/sorption and surface chemistry properties of hygienic products. He implemented the use of CTMP in the adsorption core of hygiene products

Alf de Ruvo’s achievements for the Swedish forest products industry in general, and for SCA in particular, have few parallels. He improved the relationship between industry and academia. He also initiated forest products industrial research at many academic institutions and his efforts were decisive for the development of what is now the Mid-Sweden University. He has published 79 technical papers.

He was a member of the Board of Directors of STFI, served on the board of the Swedish Forest Industries Federation, and was Chairman of the Board of the Forest Products Industry Research College (FPIRC) at the Royal Institute of Technology (KTH).

In recognition of extreme contributions to the Pulp and Paper Industry, the Swedish Association of Pulp and Paper Engineers awarded him its prestigious Ekman Medal in 1998.

Alf de Ruvo died on September 23, 2000. A foundation was organized in his honor that awards a scholarship of 500,000 Swedish Krona (SEK) in his name every year.

Martin Keyes

Martin Keyes was born on February 19, 1850 in Lempster, New Hampshire. He showed an early aptitude for invention by designing a new type of fishing reel as well as a line of furniture.  He worked with his brother to continue the family business, but became more interested in what could be done with wood.

This led him to join the Indurated Fiber Company of North Gorham, Maine that manufactured tubs, pails and pressed pulp wares. As Superintendent of Indurated, he obtained a number of patents providing protection for some of the company products.

Following an observation that workmen used pieces of veneer for plates, Keyes conceived the idea for developing plates of molded pulp.  He was eventually able to develop and patent a machine capable of making pulp molded pie plates.  Following some litigation to secure patent protection, Keyes was able to identify a pulp supplier and obtain financial backing to build a small mill in Shawmut, Maine. The first shipment of pie plates occurred in the summer of 1904, but the plant closed for a period in early 1905. Although the pie plates were superior to the competition, they were more expensive and not competitive.

After implementing significant price reduction steps and investing additional personal finances, Keyes was able to restart production.  Popularity of the pie plates increased significantly as a result of the 1906 San Francisco earthquake which created a market for disposable dishes.

By 1908, Keyes Fiber had built a new mill in Waterville, Maine and had expanded the product line to include butter dishes and a “Picnic Package” that included different size plates.  In 1911, Keyes convinced his son-in-law, Dr. George Averill to join the company. He later succeeded Keyes as head of the company and the popularity of Keyes products has continued.  Keyes Fiber also expanded the product line to include rough, as well as smooth, molded pulp products for both the commercial and consumer markets.

Today, Keyes Fiber is part of Hutamaki, Waterville, Maine, and they continue to produce a variety of pulp-molded products including the well-known Chinet® items.

Martin Keyes died on November 18, 1914 in Fairfield, Maine.

Marja-Sisko Ilvessalo-Pfaffli

Marja-Sisko Ilvessalo-Pfäffli was born in Helsinki, Finland in 1916. She earned her M.Sc. degree from the Technical University of Helsinki in 1943 and started a career that lasted 68 years. In 1956, Ilvessalo-Pfäffli married Samuel Pfäffli, Licentiate of Technology.
Ilvessalo-Pfäffli’s career started at KCL (Finnish Pulp and Paper Research Institute) in Helsinki, Finland followed by STFI in Stockholm, Sweden, Wiggins Teape in Scotland and back to KCL again. In 1954, she was appointed head of microscopy research of pulp and paper and board at KCL. In her last position at KCL, she held the right to sign officially (Per procuram) the fiber analysis documents on behalf KCL. Samples from all over the world were sent for analysis to Ilvessalo-Pfäffli, an internationally highly regarded specialist. Formally she retired when she was 65 but for a number of years continued coming to the institute every morning in the same manner as she had always done.
The value of fiber analysis has rather increased than diminished. Ilvessalo-Pfäffli developed the methodology responding to such needs and making full use of the fascinating development of the scanning electron microscopes that she was able to witness during her long career. She also developed a semi-automatic recorder for the measurement of fiber dimensions.
Later, Ilvessalo-Pfäffli worked privately concentrating in writing and editing her book Fiber Atlas that can be regarded as a “Bible” for fiber microscopists. This book comprises 400 pages and 385 figures and is an excellent guide for anybody involved in fiber analysis. It is a masterwork providing information not only on the structure of the fibers but also on the geographic distribution of the relevant tree species. It covers 29 wood samples from Eurasia, 39 from North America, 16 from the southern hemisphere and the tropics and 34 of non-wood origin. The first edition was sold out long ago but the second will come out soon. Besides Fiber Atlas, Ilvessalo-Pfäffli published a number of papers, gave presentations, participated in permanent and ad hoc working groups and was “mother”, mentor and teacher of several younger scientists, some of whom became her successors.
She was one of the very first prominent women in the world of papermakers. Twice she was given merit awards by the Finnish Paper Engineers Association.
Marja-Sisko Ilvessalo-Pfäffli died on April 3, 2013. She and her husband Samuel Pfäffli had two daughters, Heidi and Elisa.
