Sir Peter Brian Medawar (February 28, 1915 – October 2, 1987) was a Brazilian-born English scientist best known for his work on how the immune system rejects or accepts organ transplants. He was co-winner of the 1960 Nobel Prize in Physiology or Medicine with Sir Frank Macfarlane Burnet.
Early years
Medawar was born on
February 28,
1915, in
Rio de Janeiro of a British mother and a Lebanese father.
Medawar was educated at
Marlborough College, England, where he went in 1928. Leaving this College in 1932, he went to
Magdalen College,
Oxford, to study
zoology under Professor
J. Z. Young where he gained admission of
Christopher Welch Scholarship and senior Demyship to back up his scientific research. After taking his bachelor's degree at Oxford, Medawar worked for a time at
Sir Howard Florey's School of Pathology at Oxford and there became interested in research in fields of biology that are related to medicine.
Early research
Medawar's earlier research, done at Oxford, was on
tissue culture, the regeneration of
peripheral nerves and the
mathematical analysis of the changes of shape of
organisms that occur during this development. During the early stages of the
Second World War he was asked by the
Medical Research Council to investigate why
skin taken from one human will not form a permanent
graft on the skin of another person,and this work enabled him to establish theorems of transplantation immunity which formed the basis of his further work on this subject. His involvement with
transplant research began in 1949, when Burnet advanced the hypothesis that during
embryonic life and immediately after birth,
cells gradually acquire the ability to distinguish between their own
tissue substances and unwanted cells and foreign material.
Outcome of Research
Medawar was awarded his
Nobel Prize in 1960 with
Burnet for their work in tissue grafting which is the basis of
organ transplants and their discovery of acquired immunological tolerance. This work was used in dealing with
skin grafts required after
burns. Medawar's work resulted in a shift of emphasis in the science of
immunology from one that attempts to deal with the fully developed immunity mechanism to one that attempts to alter the immunity mechanism itself, as in the attempt to suppress the body's
rejection of organ transplants.
Achievements
Medawar was professor of zoology at the
University of Birmingham (1947-51) and
University College London (1951-62). In 1962 he was appointed director of the
National Institute for Medical Research, and became professor of experimental medicine at the Royal Institution (1977-83), and president of the
Royal Postgraduate Medical School (1981-87). Medawar was a scientist of great inventiveness who was interested in many other subjects including
opera,
philosophy and
cricket. He was a writer of great fluency, clarity and wit. His books are among the very best examples of a great scientist explaining the beauty and meaning of science in a manner valuable to fellow scientists as well as to laymen. His books include
The Art of the Soluble, a book of essays, some later reprinted in
Pluto's Republic,
Advice to a Young Scientist,
Aristotle to Zoos (with his wife
Jean Shinglewood Taylor),
The Life Science, and his last, in 1986,
Memoirs of a Thinking Radish, a brief autobiography. He was
knighted in 1965 and awarded the
Order of Merit in 1981. Medawar died in 1987 as the result of a series of several cerebrovascular accidents.
