John Schrank
John Flammang Schrank (born Johann Nepomuk Schrank; March 5, 1876 – September 15, 1943) was a German-American tavern owner who attempted to assassinate former President Theodore Roosevelt outside of the Gilpatrick Hotel in Milwaukee on October 14, 1912. Schrank claimed to have experienced visions of the ghost of assassinated U.S. President William McKinley, telling Schrank that Roosevelt was his murderer, and that Schrank needed to avenge his death, as well as prevent Roosevelt from being elected to a third term as President of the United States.
