Alfred Day Hershey was an American Nobel Prize–winning bacteriologist and geneticist.
He was born in Owosso, Michigan and received his B.S. in chemistry at Michigan State University in 1930 and his Ph.D. in bacteriology in 1934, taking a position shortly thereafter at the Department of Bacteriology at Washington University in St. Louis.
He began performing experiments with bacteriophages with Italian-American Salvador Luria, German Max Delbruck, Indian-Canadian Adam Hasnain, and Serbian Mila Huhtala in 1940, and observed that when two different strains of bacteriophage have infected the same bacteria, the two viruses may exchange genetic information.
