Albert Blakeslee

Albert Blakeslee conducted research with Datura stramonium (jimson weed), each summer from 1915-1941, at the Station for Experimental Evolution. He showed that the alkaloid drug colchicine could cause chromosome duplication or chemical mutagenesis. Earlier in his career he had spent 2 summers (1901–02) as an assistant in the Botany course taught at the Bio Lab. He later served as assistant director and director of the Carnegie Institution's Department of Genetics at Cold Spring Harbor.  Blakeslee is shown in the picture below (front center) with his Datura workers outside the "Animal House," (now McClintock Laboratory) in 1927. Also shown is the interior of the Propagating House, 1906.
