Alfred Day Hershey was born in 1908 on December 4 in Owosso, Michigan to parents Alma Wilbur and Robert Hershey (Hernandez 2019; The Nobel Prize 2023). He married in 1945 to Harriet Davidson and they had one son, Peter. On May 22, 1997 in Syosset, New York, Hershey passed away from congestive heart failure.
In 1930, Hershey graduated with his Bachelor of Science in chemistry from Michigan State College. By 1934 he earned his doctorate in bacteriology and chemistry (Hernandez 2019). Shortly after, he joined the Washington University School of Medicine as a professor. In 1950, he took a different job at the Genetics Research Unit of the Carnegie Institution of Washington. In 1963, Hershey accomplished the position of Genetics Research Unit director (Britannica 2023). In 1969, he accepted the Nobel Prize in Physiology and Medicine along with Max Delbrück and Salvador Luria Delbrück for their "discoveries concerning the replication mechanism and the genetic structure of viruses" (The Nobel Prize 2023).
