Alfred Day Hershey
(December 4, 1908 – May 22, 1997) was an American Nobel Prize
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
and German Max Delbrück
in 1940, and observed that when two different strains of bacteriophage have infected the same bacteria, the two viruses
may exchange genetic information
He moved with his wife Harriet to Cold Spring Harbor, New York
, in 1950 to join the Carnegie Institution of Washington
's Department of Genetics, where he performed the famous 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 Nobel Prize in Physiology or Medicine
in 1969, shared with Luria
for their discovery on the replication of viruses and their genetic structure.
Hershey had 1 child with his wife Harriet (often called Jill), a son named Peter. The family was active in the social network of Cold Spring Harbor Laboratories and regularly enjoyed the beach in season.
After Hershey died , another phage worker, Frank Stahl
, wrote: "The Phage Church, as we... Read More
