Garland E. Allen
Allen was raised in Kentucky and graduated from the University of Louisville in 1957. He completed his PhD in the history of science at Harvard University in 1966 under the direction of Ernst Mayr and Everett Mendelsohn after spending a few years as a high school biology teacher. He has taught at Washington University and has held several visiting professorships at Harvard.
Thomas Hunt Morgan
To date, Allen has offered the fullest treatment of the life and work of Thomas Hunt Morgan, himself of Kentucky native. Allen's extensive review of Morgan presents the story of an experimentalist who staunchly avoided open political ties to science for fear of biasing the research. His discussion of the fly room, first at Columbia, then at Caltech, suggests that the collaborative environment within which Morgan worked with his students, H.J. Muller, Alfred Sturtevant, Calvin Bridges, and Theodosius Dobzhansky played an important role in establishing Drosophila melanogaster as a model organism for genetics, and launching the careers of these titans of 20th century genetics. Allen's work contributes to the body of history chronicling the emergence of American science.
Allen is an international leader on the history of eugenics. His work suggests that eugenics movements were not merely localized to Germany, Britain and America, but rather that eugenics constituted an international ideological shift from social darwinism, whereby nature would weed out people with poor heredity, to an ideology where humanity must control its own genetic stock. He has suggested that with the unveiling of the human genome, we should be cautious of a new wave of the eugenics movement.
