Frank Ramsey


Frank Ramsey, who first proved Ramsey theory in 1928, was a remarkable man. He grew up in Cambridge, England. In 1925 young Ramsey graduated as the university's top mathematics student. Although philosophy and mathematical logic chiefly engaged him, he also contributed to economics, probability, decision theory, cognitive psychology and semantics, and always with keen insight and intelligence. Ramsey wrote only two papers on mathematical economics, but both are widely quoted in mathematical economics literature. Tragically, in 1930, at the age of 26, Ramsey took ill and died of complications from abdominal surgery, at the height of his intellectual powers. An irony is attached to the story of how, two years before his death, Ramsey derived his eponymous theory.
