Google on 28 October 2014 celebrated the 100th birthday of Dr Jonas Salk with a doodle on its homepage. Dr Jonas Salk was the American scientists who developed the first successful polio vaccine.
In the Google Doodle two children holding up a sign reading Thank you, Dr Salk! - a tribute to the virologist's work against a disease whose main victims were children.
In the two years before his vaccine was made widely available, the average number of polio cases in the US was more than 45000. By 1962, that number had dropped to 910.
About the polio vaccine
The virologist's research soon caught the attention of Basil O'Connor, president of the National Foundation for Infantile Paralysis whose organisation funded Salk's efforts to develop a vaccine against the devastating disease.
The resulting vaccine was tested first in monkeys and then in patients at the D.T. Watson Home for Crippled Children who already had polio.
Salk re-worked the established idea of a vaccine by suggesting that immunity could be established in the body by using inactivated viruses.
About Dr Jonas Salk
Salk graduated from New York University School of Medicine in 1939 with his M.D. degree and soon started work as a staff physician at Mount Sinai Hospital in New York City.
He would then apply his talents to the field of research, becoming a fellow at the University of Michigan where he worked to develop a flu vaccine at the request of the US Army.
By 1947, he was appointed director of the Virus Research Laboratory at the University of Pittsburgh school of Medicine, the institution where he developed the techniques that would help him discover a vaccine for polio.
His Honors and recognitions
• In 1955, scholarship fund was announced by City University of New York city. It creates the Salk Scholarship fund which was awarded to multiple outstanding pre-med students each year.
• In 1958, he was elected to the Polio Hall of Fame, which was dedicated in Warm Springs, Georgia.
• In 1975, he was awarded the Jawaharlal Nehru Award and the Congressional Gold Medal.
• In 2012, in honor of his birthday, 24 October has been named "World Polio Day", and was originated by Rotary International over a decade earlier.
In early 2009, the American Public Broadcasting Service (PBS) aired its new documentary film, American Experience: The Polio Crusade.
In April 2010, to help celebrate the 55th anniversary of the Salk vaccine, a new 66-minute documentary, The Shot Felt 'Round the World', had its world premiere.
In 2014, actor and director Robert Redford, who was once struck with a mild case of polio when he was a child, directed a documentary about the Salk Institute in La Jolla, California.
