☆ Born October 28, 1914 ☆
Dr. Jonas Salk led the medical research team at the University of Pittsburgh that developed the first safe and effective vaccine against polio. The vaccine underwent initial testing among school-aged children in the Pittsburgh area, and after its introduction in 1955, it rapidly brought epidemics of polio in the United States under control. The vaccine continues to be used in the global effort to eradicate the paralyzing disease.
