Sir Peter Brian Medawar OM CH CBE FRS (/ ˈ m ɛ d ə w ər /; 28 February 1915 – 2 October 1987) was a British biologist and writer, whose works on graft rejection and the discovery of acquired immune tolerance have been fundamental to the medical practice of tissue and organ transplants.
Peter Medawar was a British zoologist who pioneered research on transplantation immunity and skin grafting. He was born in Rio de Janeiro in 1915 and died in London in 1987.
Peter Medawar discovered acquired immunological tolerance by transplanting tissue between mouse fetuses without rejection. He shared the prize with Macfarlane Burnet for their contributions to immunology.
Sir Peter B. Medawar was a Brazilian-born British zoologist who received, with Sir Frank Macfarlane Burnet, the Nobel Prize for Physiology or Medicine in 1960 for developing and proving the theory of acquired immunological tolerance, a model that paved the way for successful organ and tissue.
3 mars 2015 · Learn how Peter Medawar, a zoology graduate and a former student of Howard Florey, made the first discoveries that led to his Nobel Prize for physiology or medicine in 1960. His research on tissue transplantation and immune system opened the door to organ transplantation and won him acclaim as a science communicator.
During his final years in the laboratory, Medawar turned his attention to cancer research, focusing primarily on immunopotentiation as a means of stopping tumor growth. Medawar also established himself as a remarkably articulate and witty science writer.
