Lynn Townsend White Jr. (April 29, 1907 – March 30, 1987) was an American historian. He was a professor of medieval history at Princeton from 1933 to 1937, and at Stanford from 1937 to 1943. He was president of Mills College, Oakland, from 1943 to 1958 and a professor at University of California, Los Angeles from 1958 until 1987. Lynn White helped to found the Society for the History of Technology (SHOT) and was president from 1960 to 1962. He won the Pfizer Award for "Medieval Technology and Social Change" from the History of Science Society (HSS) and the Leonardo da Vinci medal and Dexter prize from SHOT in 1964 and 1970. He was president of the History of Science Society from 1971 to 1972. He was president of The Medieval Academy of America from 1972–1973, and the American Historical Association in 1973. Biography White began his career as medieval historian focusing on the history of Latin monasticism in Sicily during the Norman Period but realized the coming conflict in Europe would interfere with his access to source materials. While at Princeton he read the works of Richard Lefebvre des Noëttes, and Marc Bloch. This led to his first work in the history of technology, "Technology and Invention in the Middle Ages" in 1940. Noettes was a retired French cavalry officer who made his hobby the history of horses. He wrote that the utilization of animals in antiquity was inefficient because the ancients were limited by the technologies of their period, specifically the lack of horseshoes and a bad harness design. White expanded Noettes’ conclusions into a thesis of his own that encompassed the relationship of the newly realized efficient horse and the agricultural revolution of the time. White pointed to new methods of crop rotation and plowing and tied them to the rise of manor-based collective farming and the shift in European prosperity and power from the Mediterranean to the North. White also touched on the stirrup, the lateen sail, the wheel barrow, the spinning wheel, the hand crank, water-driven mills and wind mills. He concluded: "The chief glory of the later Middle Ages was not its cathedrals or its epics or its scholasticism: it was the building for the first time in history of a complex civilization which rested not on the backs of sweating slaves or coolies but primarily on non-human power" and he credited this as
