SHOT President: 1986 to 1988
da Vinci Medal: 1995
Bruce Sinclair, for more than fifty years an honored presence in the Society for the History of Technology, passed away at his Point Richmond, California, home on March 15, 2025. Bruce and his fraternal twin brother Jerry were born in 1929, the last two of five children born to Bert and Helen Sinclair. By the mid-1930s, the family had settled in Vallejo, California, and then in nearby Napa, where Bert was a partner in the Berry & Sinclair Photography Studio. The pull of war work brought the family to Richmond, where thousands were employed in shipbuilding and where Bruce graduated from high school. His college education at the University of California was interrupted when he enlisted in the Air Force at the time of the Korean War. He served primarily in electronic countermeasures, monitoring Soviet nuclear testing from occupied Japan and then U.S. nuclear testing in Nevada. Upon his discharge, Bruce returned to his studies with new enthusiasm, earning a bachelor’s degree from Berkeley, a master’s from New Mexico Highlands University, and a second master’s from the University of Delaware’s new Hagley Program in Industrial History. His Hagley degree in hand, he became the founding director of the Merrimack Valley Textile Museum in North Andover, Massachusetts. There he met and married Christine Roen in 1956, and they had two children, Alan and Margaret.
From 1957 to 1959 Bruce served as a fellow at the Hagley Foundation, and he then moved to Cleveland, earning his Ph.D. in 1964 from Mel Kranzberg’s new program in the history of technology at Case Institute. His Case mentors were Kranzberg and Edwin Layton, and at the University of California campus in Santa Barbara, Carroll Pursell played a critic’s role for Bruce as well. Bruce’s Case doctorate launched him into a lifelong engagement teaching the history of technology and engineering. He first joined the faculty and then became Chair of the History Department of Kansas State University in Manhattan, and in 1969 he began a long career as a professor and then director of the Institute for the History and Philosophy of Science and Technology at the University of Toronto. 1988 was a banner year for Bruce. He and Gail Ann Cooper, a student of Pursell’s, were married, and at the Georgia Institute of Technology, Bruce was named as its first Melvin Kranzberg Professor for the History of Technology. At Tech he guided the development of a new and important program.
Bruce’s scholarship was wide-ranging. His oft-reprinted Technology and Culture article titled “At the Turn of a Screw: William Sellers, the Franklin Institute, and a Standard American Thread,” and his Dexter Prize winning 1974 book, Philadelphia’s Philosopher Mechanics: A History of the Franklin Institute 1824-1865 are both landmarks in the history of technology. Similarly, his Centennial History of the American Society of Mechanical Engineers 1880-1980 became a model in the world of public history, and in 2004 his Technology and the African American Experience broke new ground. Bruce served as SHOT’s president from 1986 to 1988, and in 1995 he was awarded the society’s Leonardo da Vinci Medal for his distinguished work as a scholar, teacher, and museum professional. Beyond that, Bruce was a friend and mentor to many young scholars. After his retirement, he and Gail lived in Bethlehem, Pennsylvania, where she was a professor of the history of technology at Lehigh University. Early in the 21st century, Bruce and Gail both served as Dibner Institute fellows in Cambridge.
Bruce was always an enthusiastic sailor. While in Toronto, he cruised in a Folkboat on Parry Sound with his second wife Mary Pickard Winsor, and then he sailed alone to the Bahamas as an homage to his son Alan, who died at the age of 23. Bruce owned a series of boats, but he was especially fond of two that he sailed on San Francisco Bay after he and Gail moved to California. They were called Pretty Penny and The Shadow, sisterships built by Hank Easom to a Gary Mull design. I had the good fortune of Bruce’s company as my first mate when I sailed my boat from Annapolis, Maryland, to Oriental, North Carolina, in 2008, and I still have his handwritten log of that trip. There was nothing finer, thought Bruce, than “messing about on boats,” and his winning of an important race in the Lipton Cup Series for the Vallejo Yacht Club at the age of 80 must surely have given him a lot of pleasure.
Bruce is survived by his daughter, Margaret Vargas, and her descendants, as well as by Gail, his beloved wife of 36 years. His siblings left him with many nieces and nephews, all of whom remember their Uncle Bruce fondly. But not least of all, Bruce will be remembered fondly by academic colleagues, and by sailors, everywhere.
