Jonas Salk (1914-1995), “the man who saved the children,” developed a vaccine for polio, a terrifying disease that crippled and killed people. In the 1950s, when tens of thousands of children were infected each year, Dr. Salk worked in his laboratory sixteen hours a day, seven days a week, searching for a way to stop the epidemic. Volunteering to be among the first “human guinea pigs,” he injected himself with his experimental vaccine to prove it was safe and effective. Fueled by remarkable idealism, he refused to patent his vaccine so that it could be distributed freely around the world.
“Hope lies in dreams, in imagination and in the courage of those who dare to make dreams into reality.” - Jonas Salk
