Born 19 Dec 1903; died 6 Jun 1996 at age 92.American geneticist, known as the "father of immunogenetics," who paved the way for modern organ transplants. He shared the 1980 Nobel Prize for Physiology or Medicine for his studies of the genetic factors of histocompatibility which govern transplanting tissue from one individual to another. Snell identified the factors responsible as the major histocompatibility complex (MHC) - an assortment of antigens (which cause the production of antibodies) common across the genetic makeup of all vertebrates.
