Salk, Jonas Edward (1914-1995), American physician and epidemiologist, who developed the first vaccine against poliomyelitis. Salk was born in New York City. His work on an anti-influenza vaccine led him and his colleagues to develop an inactivated vaccine against polio in 1952. After successful wide-scale testing in 1954, the vaccine was distributed nationally, greatly reducing the incidence of the disease. In the mid-1950s American virologist Albert Sabin developed an oral, attenuated (live) vaccine, which brought polio under control.
JONAS SALK, "Matter at each
level of complexity appears to consist of two interdependent, nonidentical
elements in dynamic
interaction and in integral relation to each other. It appears that an interacting, dynamic, asymmetrical binary relationship is the fundamental module of order in the cosmos. I have the impression that the interactions in these dynmamic asymmetrical binary systems underlie all phenomena in nature...The most fundamental phenomena in the universe is relationship. It then becomes possible to recognize the underlying unity in all the diversity of the phenomena of life."
