Alfred Day Hershey Biography
Birthday: December 4, 1908 (Sagittarius)
Born In: Owosso, Michigan, United States
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.
