About Peter Medawar

Peter Brian Medawar (1915-1987) was a prominent British zoologist and immunologist, renowned for his groundbreaking contributions to the field of immunology, particularly in the areas of transplantation biology and vaccination. Born on February 28, 1915, in Trieste, Italy, Medawar was the son of an Armenian-Italian father and a British mother. His family moved to London when he was four years old, where he grew up. As a child, Medawar's fascination with science began, particularly after reading H.G. Wells' "The Time Machine" at the age of nine. Medawar attended University College London, where he studied mathematics and physics. However, it was his move to Magdalene College, Cambridge, in 1936 to study zoology that marked a pivotal point in his life. There, under the influence of influential biologists like J.B.S. Haldane and John Burdon Sanderson Haldane, Medawar's interest in immunology was sparked. In 1944, Medawar published "An Unsolved Problem in Connexion with the Transplantation of Tissue and Organs," a paper that challenged prevailing theories about tissue rejection. This work laid the foundation for his future research on immunology and transplantation biology. Medawar's most significant contribution to science came in 1953, when he and his colleague, R.A. Good, developed the theory of acquired immune tolerance, which fundamentally changed our understanding of how the immune system functions. In addition to his scientific work, Medawar was also a prolific writer and speaker. He authored several books, including "The Art of the Soluble" (1968) and "Advice to a Young Scientist" (1979), which offer insights into the nature of scientific creativity, the philosophy of science, and the importance of skepticism in scientific research. Medawar was awarded the Nobel Prize in Physiology or Medicine in 1960 for his work on immune transfusion and its relation to the genetics of the adaptive response. He passed away on October 4, 1987, leaving behind a rich legacy in immunology and science education.

Interpretations of Popular Quotes

"Science is a dictionary. Research is looking up words you don't know."

This quote by Peter Medawar suggests that science, as a body of knowledge, is like a comprehensive dictionary, containing established facts, theories, and concepts. However, the act of research is more dynamic, involving the exploration of new ideas or unknown areas within this science "dictionary." By looking up words one doesn't know (research), scientists expand their understanding, make discoveries, and move forward in the pursuit of knowledge.


"The first duty of a scientist is to be wrong as quickly as possible."

Peter Medawar's quote, "The first duty of a scientist is to be wrong as quickly as possible," emphasizes the importance of admitting and correcting errors promptly in scientific research. In essence, this statement highlights the significance of an open, iterative approach where scientists aim to disprove their own hypotheses or findings as soon as possible. By doing so, they can ensure that their work is based on accurate data and avoid building upon flawed foundations, ultimately contributing to the progression of scientific knowledge more efficiently.


"An honest man is always a child."

The quote "An honest man is always a child" by Peter Medawar suggests that an individual who maintains integrity, curiosity, and openness to new ideas throughout their life possesses qualities reminiscent of a child's natural state. This childlike trait encompasses a lack of pretense or deceit, an unbiased approach to learning, and a readiness to embrace change and uncertainty. Thus, the quote encourages us to retain our honesty and curiosity as we grow older, fostering an appreciation for humility, open-mindedness, and the childlike wonder that drives continuous growth and discovery.


"A good scientist is a man who is too intelligent to believe everything he is told and too honest to conceal his skepticism."

This quote by Peter Medawar highlights the crucial role of critical thinking in the scientific process. A good scientist should not blindly accept established ideas, but instead, question them, test their validity, and maintain an open-minded yet skeptical attitude. The honest expression of doubt fosters progress and allows for the continual improvement and refinement of scientific knowledge.


"Science is the antidote to prejudice, superstition, ignorance, and fear."

This quote by Peter Medawar emphasizes that science serves as a powerful tool against irrational beliefs and unfounded fears. By systematically questioning, investigating, and analyzing phenomena, science provides objective evidence and understanding that can dispel prejudice, superstition, ignorance, and fear. In other words, science offers a rational approach to the world, allowing us to make informed decisions, break down barriers, and promote knowledge as a means of empowerment and progress.


I cannot give any scientist of any age better advice than this: the intensity of a conviction that a hypothesis is true has no bearing over whether it is true or not.
