Salk, who developed the first polio vaccine, poses in his laboratory in Pittsburgh, Pa., April 7, 1955. Poliomyelitis, known as polio, causing paralysis and death, was a virus that swept the United States from 1942-1953. President Franklin D. Roosevelt was left partially paralyzed when he contracted the disease as an adult. The epidemic peaked in 1950 when over 33,000 cases were reported, and the virus spread to Asia and Europe. The Salk Institute was established in California in 1963 asa research center for immunology, virology and geneology, with Salk as its president. (AP Photo) (ASSOCIATED PRESS)
