Daniel_F._Steck--Dick_Clark_(senator)

Daniel Frederic Steck (December 16, 1881 – December 31, 1950), was the only Iowa Democrat in the United States Senate between the American Civil War and the Great Depression. He was sworn in as senator only after an extraordinary election challenge, in which his apparent defeat at the polls by a Progressive Party ally running as a Republican was reversed by a Republican-controlled U.S. Senate over seventeen months later.
