He was born in Owosso, [[Michigan]] and received his B.S. in chemistry at [[Michigan State University]] in 1930 and his Ph.D. in [[bacteria|bacteriology]] in 1934, taking a position shortly thereafter at the Department of Bacteriology at [[Washington University in St. Louis]]. He began doing experiments with [[bacteriophage]]s with Italian-American [[Salvador Luria]] and German [[Max Delbrück]] in 1940. He found that when two different strains of bacteriophage have infected the same bacteria, the two [[virus]]es may exchange [[genetics|genetic]] information. He moved with his wife Harriet to [[Cold Spring Harbor, New York]], in 1950 to join the [[Carnegie Institution for Science]]'s Department of Genetics. There he performed the famous [[Hershey-Chase experiment|Hershey-Chase blender experiment]] with [[Martha Chase]] in 1952. This experiment provided additional evidence that [[DNA]], not [[protein]], was the genetic material. He became director of the Carnegie Institution in 1962 and was awarded the
