Robert Ferdinand Wagner III (January 6, 1944 – November 15, 1993, aged 49) was an American politician and public servant. He was a New York City civic leader who served as the Deputy Mayor of the City of New York, and President of the New York City Board of Education. He is often confused with his father of the same name, Robert F. Wagner Jr., who served as Manhattan Borough President and Mayor of the City of New York during Robert III’s youth. He was also the grandson of Senator Robert Ferdinand Wagner I. He changed his name to Robert F. Wagner Jr. after his father dropped the “Jr”.
