John T. Hoffman

23rd Governor, 1869-1872
John T. Hoffman

Prior to his election as governor, John T. Hoffman (1828–1888) served as mayor of New York City. As governor, Hoffman signed legislation to create the American Museum of Natural History and The Metropolitan Museum of Art. He ordered protection for marchers during New York City’s Orange Riot, a violent conflict between Irish Protestants and Catholics in which more than 60 people were killed. Hoffman’s association with the corrupt boss of the Tammany Hall political machine, William M. Tweed, hastened the end of his political career.
