Jonas Edward Salk
Jonas Edward Salk (1914 – 1995), famous medical researcher and virologist. He discovered and developed the first successful inactivated polio vaccine. When news of the vaccine’s success was made public on April 12, 1955, Salk was hailed as a “miracle worker” and the day almost became a national holiday. Around the world, an immediate rush to vaccinate began, with countries including Canada, Sweden, Denmark, Norway, West Germany, the Netherlands, Switzerland, and Belgium planning to begin polio immunization campaigns using Salk’s vaccine. His sole focus had been to develop a safe and effective vaccine as rapidly as possible, with no interest in personal profit. When asked who owned the patent to it, Salk said, “There is no patent. Could you patent the sun?” In 1960, he founded the Salk Institute for Biological Studies in La Jolla, California, which is today a center for medical and scientific research. He continued to conduct research and publish books, including Man Unfolding (1972), The Survival of the Wisest (1973), World Population and Human Values: A New Reality (1981), and Anatomy of Reality: Merging of Intuition and Reason (1983). Salk’s last years were spent searching for a vaccine against HIV. His personal papers are stored at the University of California, San Diego Library.[
