Dorothy Maud Wrinch (1894–1976), mathematician, philosopher, and theoretical biologist. She studied mathematics and philosophy at Girton College, Cambridge, and came under BR’s influence in her second year when she took his course on mathematical logic. She taught mathematics at University College, London, 1918–21, and then at Oxford, 1922–30. Her first publications were in mathematical logic and philosophy, and during the 1920s she wrote on the philosophy of science. But in the 1930s her interests turned to mathematical biology and crystallography, and in 1935 she moved to the United States on a Rockefeller Foundation fellowship and remained there for the rest of her life. Unfortunately, as a biologist she is best known for a long and stubborn controversy with Linus Pauling about the structure of proteins in which he was right and she was wrong. See Marjorie Senechal, I Died for Beauty: Dorothy Wrinch and the Cultures of Science (New York: Oxford U. P., 2013). Chapter 7 is devoted to Wrinch’s interactions with BR in Brixton.
