In 1933, Nathan joined
US Commerce Department. During this time he worked with the influential economist
Simon Kuznets, who he had also studied under at
Wharton, in implementing the first national income measurements which would later serve as the basis for the
GNP. When World War II started, Nathan frequently criticized the lack of industrial readiness should the United States enter the war. In 1942, Nathan was elected as a
Fellow of the American Statistical Association. That same year he was appointed chair of the federal
War Production Board's planning committee. A chief insight was to plan for war production based on the U.S. population rather than on the basis of the existing industrial plant. Nathan also made the case to military officials that economic mobilization would not be able to support an invasion of Europe until 1944. Growing increasingly dissatisfied with the internal politics of the War Production Board, and feeling the need to serve his country, he volunteered for the Army in May 1943, though back injuries prevented him from serving in combat. After the war. Nathan started the consulting firm Robert R. Nathan Associates (now Nathan Associates, Inc.) which conducted major economic development projects in the Middle East, Asia, and Latin America. During the 1950s, Nathan served for a period as chair of
Americans for Democratic Action. In this role, he was openly critical of
President Dwight Eisenhower's conservative policies. During subsequent decades, Nathan participated in Johnson administration efforts to further development in South Vietnam; supported Hubert Humphrey's presidential candidacy; and consulted in a number of high-profile projects, including the
Curt Flood case. == Death ==
