Leon Czolgosz, an unemployed anarchist, shoots and fatally wounds US president William McKinley at the Pan-American Exposition in Buffalo, New York.

Leon Frank Czolgosz was an American wireworker and anarchist who assassinated United States president William McKinley in 1901. Czolgosz had lost his job during the economic Panic of 1893 and turned to anarchism. He regarded McKinley as a symbol of oppression and believed that it was his duty as an anarchist to assassinate him. Czolgosz shot McKinley in Buffalo, New York, on September 6, 1901, and was immediately arrested. McKinley died on September 14 after his wound became infected. A month later, Czolgosz was convicted of first degree murder and was sentenced to death. He was executed by the electric chair on October 29.
