Jonas Salk 1914-1995 Birthplace: New York City Discovery: 1955 discovery of polio vaccine

While attending medical school at New York University, Salk was invited to spend a year researching influenza. The virus that causes flu had only recently been discovered and the young Salk was eager to learn if the virus could be deprived of its ability to infect, while still giving immunity to the illness. Salk succeeded in this attempt, which became the basis of his later work on polio. After completing medical school and his internship, Salk returned to the study of influenza, the flu virus. World War II had begun, and public health experts feared a replay of the flu epidemic that had killed millions in the wake of the First World War. The development of vaccines controlled the spread of flu after the war and the epidemic of 1919 did not recur. In 1947, Salk accepted an appointment to the University of Pittsburgh Medical School. While working there, with the National Foundation for Infantile Paralysis, Salk saw an opportunity to develop a vaccine against polio, and devoted himself to this work for the next eight years.
