A pioneer of molecular biology, Oswald Avery revolutionized science with his research on the chemical processes involved in immunology. The Canadian-American bacteriologist initially aspired to be a musician. He later proved that DNA was the basis of heredity. Though nominated for the Nobel Prize multiple times, he never won it.
Nobel Prize-winning biologist Alfred Day Hershey is best remembered for his research on bacteriophages, or viruses that infect bacteria.

Referred to as the father of modern virology, Rivers is best remembered for his association with the Rockefeller Institute for Medical Research; his work during the 1930s and 1940s helped the institute become a leader in viral research. In 1958, Rivers was made an inductee of the Polio Hall of Fame.
