Alfred Day Hershey was bornon 4 December 1908 in Owosso, Michigan, American, is Nobel Prize Winner in Medicine. Alfred Day Hershey was an American bacteriologist and geneticist who won the 1969 Noble Prize in Medicine, which he shared with Max Delbrück and Salvador Edward Luria. He discovered the fact that DNA, not protein, was the genetic material of life. His scientific accomplishments root back to his undergraduate years, when he developed a strong interest in bacteriology. He went on to earn a doctorate in his field of interest and was appointed to work with a renowned bacteriophage researcher. He was encouraged to study viruses and soon his experiments resulted in several discoveries that made advancements in understanding of genetic inheritance and change. His comprehensive studies persuaded some other scientists to collaborate with him and together they were able to unveil some important breakthroughs regarding the genetic replication information of viruses. But it was the famous ‘Hershey-Chase experiment’ also known as the ‘blender experiment’, which he conducted with his assistant Martha Chase, that placed him miles ahead of his contemporary scientists. His discovery introduced DNA as the data capsule which contains all the information of evolution. It was a path breaking accomplishment which led to many other advancements and achievements in the field of modern genetics.


He died of a heart failure on May 22, 1997 in Syosset, New York


In 1974, he retired from active research but continued visiting his research lab regularly afterwards


In 1962, he became the Director of the Genetics Research Unit of the Carnegie Institution, Cold Springs Harbor and continued his research on phage recombination and genetics


He is best known for the phenomenal ‘blender experiment’ he conducted with his colleague, Martha Chase, in 1952, which concluded that deoxyribonucleic acid (DNA), not its associated protein, is the genetic material of life


In 1950, he moved with his assistant, Martha Chase, to Cold Spring Harbor, New York and became a staff scientist in the Carnegie Institution of Washington's Department of Genetics


In 1945, he and Luria discovered, working independently, that the phage viruses and the bacteria they infect can undergo spontaneous mutations


In 1943, he received an invitation from a biophysicist, Max Delbruck, who was also pursuing the same line of investigation of phage study


During the early 1940s, he conducted his own experiments regarding immunologic reaction of phages and other factors that influenced phage infectivity


He was promoted as an assistant professor in 1938 and an associate professor in 1942


From 1936 to 1939, he and Bronfenbrenner published papers on the growth of bacterial cultures


He worked for 16 years in the Washington University, from 1934 to 1950, which included teaching and researching


He obtained his Bachelor in Science degree in Chemistry in 1930


He received his early education from the Owasso High School and after graduating from school in 1925, he was enrolled at the Michigan State College


He was born on December 4, 1908 in Owosso, Michigan, U
