Robert M. La Follette

Robert Marion La Follette Sr., nicknamed "Fighting Bob", was an American lawyer and the leading progressive politician in Wisconsin from the 1890s until his death in 1925. He served as U.S. senator from Wisconsin for the last 20 years of his life; prior to that he served as the 20th governor of Wisconsin (1901–1906) and served three terms in the U.S. House of Representatives (1885–1891). A Republican for most of his life, he ran for president of the United States as the nominee of his own Progressive Party in the 1924 United States presidential election. Historian John D. Buenker describes La Follette as "the most celebrated figure in Wisconsin history".
