John Franklin Enders received the 1954 Nobel Prize in Physiology or Medicine "for their discovery of the ability of polioviruses to grow in cultures of various types of tissue". Meanwhile, Jonas Salk applied the Enders-Weller-Robbins technique to produce large quantities of poliovirus, and then developed a polio vaccine in 1952. Upon the 1954 polio vaccine field trial, whose success Salk announced on the radio, Salk became a public hero but failed to credit the many other researchers that his effort rode upon, and was somewhat shunned by America's scientific establishment. In 1954, Enders and Peebles isolated measlesvirus from an 11-year-old boy, David Edmonston.
