Early Life

Jonas Salk was born on October 28, 1914, in New York City, where his father worked in the garment district. Education was very important to his parents, and they encouraged him to work hard in school.

Salk attended City College of New York after graduating from high school, where he earned a bachelor’s degree in science. In 1939, he received his M.D. from New York University.

Salk interned for two years at Mount Sinai Hospital before receiving a fellowship to the University of Michigan, where he studied flu viruses with Dr. Thomas Francis Jr.

Polio Vaccine

Salk accepted a position at the University of Pittsburgh in 1947, where he began researching polio, also known as infantile paralysis. By 1951, Salk had discovered three distinct types of polio viruses and had developed a “killed virus” vaccine for the disease. Polio viruses that had been grown in a laboratory and then destroyed were used in the vaccine.

The polio vaccine’s preliminary testing began in 1952, with the majority of the shots administered to children.

Over the next two years, national testing expanded, making it one of the largest clinical trials in medical history. During the testing phase, approximately 1.8 million children received the vaccine. Salk administered the experimental vaccine to himself, his wife, and their three sons in 1953.

The National Foundation for Infantile Paralysis and its president, Basil O’Connor, supported and promoted Salk’s efforts. Salk became a national hero when the vaccine was approved for widespread use in 1955. President Dwight D. Eisenhower honored him with a special citation in the White House Rose Garden.

The vaccine had a significant impact on the number of new cases of polio reported in its first few years. According to the College of Physicians of Philadelphia, there were over 57,000 cases in the United States in 1952. A decade later, the figure had dropped to less than a thousand.

Around this time, the Salk vaccine was replaced by a live virus vaccine developed by Albert Sabin, which was less expensive and easier to use.

Later Years

Salk founded his own research facility, the Salk Center for Biological Studies, in 1963. There, he and other scientists focused their efforts on diseases such as multiple sclerosis and cancer. Salk served as director of the center until 1975, when he became its founding director. Later in his career, Salk continued his research, investigating AIDS and HIV.

In addition to his research activities, Salk also wrote several books on philosophical topics. His works include Man Unfolding (1972) and The Survival of the Wisest (1973), which he co-authored with his son Jonathan.

Salk died of heart failure on June 23, 1995, at his home in La Jolla, California. With his breakthrough vaccine, Salk had earned his place in medical history. He will always be remembered as the man who put a stop to polio.

Personal Life & Wife

From 1939 to 1968, Salk was married to social worker Donna Lindsay. Peter, Darrell, and Jonathan were the couple’s three sons. He married Francoise Gilot, an artist who had previously been romantically involved with Pablo Picasso, in 1970.
