John Enders

John Franklin Enders (1897–1985) was an American virologist and microbiologist who served as Higgins University Professor at Harvard University and Chief of the Research Division of Infectious Diseases at Children's Hospital in Boston. He is best known for cultivating the poliomyelitis virus in non-nervous tissue cultures, for which he shared the 1954 Nobel Prize in Physiology or Medicine, and for subsequently developing the measles vaccine, which was licensed in 1963. He is widely regarded as a foundational figure in modern vaccinology.
