Marking the 100th birth anniversary of Jonas Salk, the man behind the polio vaccine, Google on Tuesday came out with a doodle on its home page.
Born on October 18, 1914, the American researcher and virologist was a part of a team working on a vaccine against polio in 1942. Salk later went on to head the Virus Research Lab at the University of Pittsburgh by 1947 and began preliminary testing of the polio vaccine in 1952.
Salk was able to identify three different polio viruses, which helped him develop a vaccine to combat the disease. It was in 1955 that the vaccine was declared a success.
