This hour we’re talking with Charlotte DeCroes Jacobs, author of the biography Jonas Salk: A Life (Oxford University Press, May 2015). Salk is best known for creating the polio vaccine that paved the way to eradicating the disease in the United States. Jacobs explores the extraordinary story of how Salk ran trials for the vaccine, and what he did after he achieved his life’s greatest accomplishment.
