Lewis Thomas

Born 25 Nov 1913; died 3 Dec 1993 at age 80. American physician and author best known for his reflective essays on a wide range of topics in biology. While his specialities are immunology and pathology, in his book, Lives of a Cell, his down-to-earth science writing stresses that what is seen under the microscope is similar to the way human beings live, and he emphasizes the interconnectedness of life. As a research scientist, Thomas made an impact by suggesting that an immunosurveillance mechanism protects us from the possible ravages of mutant cells, an idea later championed by Macfarlane Burnett. He also proposed that viruses have played a major role in the evolution of species by their ability to move pieces of DNA from one individual or species to another.
