A. D. Hershey: A Pioneering Biologist
On May 22, 1997, the scientific community mourned the loss of A. D. Hershey, an influential American biologist known for his groundbreaking work with bacteriophages. Born in 1908, Hershey dedicated his life to understanding viruses that infect bacteria, which laid the groundwork for modern genetics. His exceptional contributions to molecular biology were recognized with a Nobel Prize in Physiology or Medicine in 1969, shared with his collaborator, Marjorie L. Maurice.
The Impact of A. D. Hershey's Work
Hershey's experiments, particularly the famous Hershey-Chase experiment, provided critical evidence that DNA is the material of heredity. By using radioactive isotopes, he demonstrated that when bacteriophages infect bacterial cells, it is the DNA that enters the bacterial cell while the protein coat remains outside. This experiment revolutionized the understanding of genetic material and confirmed that DNA, not protein, carries genetic information.
