Called by F. Cyril James "one of the wisest of American economists during the period between the two World Wars", Robert B. Warren was the co-author of The State in Society (1939) and of The Search for Financial Security (1940). Born in Plattsburgh, N.Y., on March 15, 1891, he graduated from Hamilton College in Clinton, before going to Harvard. He worked for the Federal Reserve Board of Washington (1922-1926) and the Federal Reserve Bank of New York (1926-1927) before joining Case, Pomeroy & Co. of New York as economist and vice-president (1928-1938). In 1939, he joined the Institute for Advanced Study of Princeton University and worked also as consultant to the U.S. Treasury between 1942 and 1945. His papers were passed to Cyril James, with a request by the Rockefeller Foundation to write a critical biography of Warren. Pressure of work made it impossible for James to complete the work.
