Church, Alonzo. " Uniqueness of the Lorentz Transformation". Mathematical Association of America, 1924. 1st edition. Published in the American Mathematical Monthly, vol 31, number 8, October 1924 8vo. Fine condition. We offer the rare monthly issue of the AMM containing Church's contribution on pp 376-382. This is Church's first published work (in a career in which he published over EIGHT decades and 71 years), complete when he was 22, just two years before he received his PhD from Princeton. He would of course stay on at Princeton and have one of the most important American careers in logic in the 20th century. Enderton (and the St, Andrews mathematics website) on the atmosphere at Princeton during its heydey in the 1930's: "Princeton in the 1930's was an exciting place for logic. There was Church together with his students Rosser and Kleene. There was John von Neumann. Alan Turing, who had been thinking about the notion of effective calculability, came as a visiting graduate student in 1936 and stayed to complete his Ph.D. under Church. And Kurt Gödel visited the Institute for Advanced Study in 1933 and 1935, before moving there permanently."
