Between 1907 and 1915 Albert Francis Blakeslee transformed both himself and the Connecticut Agricultural College at Storrs into things neither had been at the beginning of the century. Using the varied commitments of the agricultural college and experiment station at which he worked as resources with which to build his career, Blakeslee began as a botanist and instructor in botany and ended as a geneticist and teacher of genetics. Moreover, he left behind at Storrs a legacy of genetic research and (...) instruction in the form of an autonomous department of Botany and Genetics. The story of Blakeslee's career at the Connecticut Agricultural College reveals the multifold ways in which agricultural researchers identified unique institutional resources and built unexpected careers and unanticipated institutional structures, a process which had a significant impact on the disciplinary growth of genetics in the United States.
