Chester Alan Arthur (October 5, 1829 – November 18, 1886) was an American attorney and politician who served as the 21st president of the United States from 1881 to 1885. Previously the 20th vice president, he succeeded to the presidency upon the death of President James A. Garfield in September 1881, two months after Garfield was shot by an assassin. Although Arthur had worked closely with Dorsey before his presidency, once in office he supported the investigation and forced the resignation of officials suspected in the scandal. An 1882 trial of the ringleaders resulted in convictions for two minor conspirators and a hung jury for the rest.
