Ralph Harold Metcalfe Sr. was an American track and field sprinter and politician. He jointly held the world record in the 100-meter dash and placed second in that event in two Olympics, first to Eddie Tolan in 1932 at Los Angeles and then to Jesse Owens at the 1936 Olympics in Berlin, Germany. Metcalfe won four Olympic medals and was regarded as the world's fastest human in 1934 and 1935. He later went into politics in the city of Chicago and served in the United States Congress for four terms in the 1970s as a Democrat from Illinois.
