Robert Marion "Fighting Bob" La Follette Sr. (June 14, 1855 – June 18, 1925) is widely regarded as Wisconsin’s most distinguished political leader. He served in the U.S. House of Representatives from 1885 to 1891, as Wisconsin governor from 1900 to 1906, and in the U.S. Senate from 1906 until his death in 1925. He was one of the founders of the national Progressive Party and was that party’s candidate for president in 1924. A national poll of historians and senators in 1957 named La Follette one of five most distinguished nonliving senators. This day is observed if school is in session.
