Alfred Sturtevant

Alfred Henry Sturtevant was an American geneticist. Sturtevant constructed the first genetic map of a chromosome in 1913. Throughout his career he worked on the organism Drosophila melanogaster with Thomas Hunt Morgan. By watching the development of flies in which the earliest cell division produced two different genomes, he measured the embryonic distance between organs in a unit which is called the sturt in his honor. In 1967, Sturtevant received the National Medal of Science.

Alfred Henry Sturtevant was born in Jacksonville, Illinois, United States on November 21, 1891, the youngest of Alfred Henry and Harriet Sturtevants six children. His grandfather Julian Monson Sturtevant, a Yale University graduate, was a founding professor and second president of Illinois College, where his father taught mathematics.
