Jonas Edward Salk (October 28, 1914 – June 23, 1995)
On March 26, 1953, American medical researcher Dr. Jonas Salk
(above) announced that he had successfully tested a vaccine
against poliomyelitis, the virus that causes the crippling disease
of polio.
In 1952—an epidemic year for polio—there were 58,000 new cases reported in the United States, and more than 3,000 died from the
disease.
For his work in helping to eradicate the disease, which is known
as “infant paralysis” because it mainly affects children, Dr. Salk
was celebrated as the great doctor-benefactor of his time.
