[Ellen Herndon Arthur, head-and-shoulders portrait, facing front] / W. Kurtz, New York.

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 (1881–85). He succeeded James A. Garfield upon the latter's assassination. The son of a Baptist preacher who had emigrated from northern Ireland, Arthur was born in Fairfield, Vermont, in 1829. He was graduated from Union College in 1848, taught school, was admitted to the bar, and practiced law in New York City. Early in the Civil War he served as Quartermaster General of the State of New York. Suffering from poor health, he retired at the close of his term. Journalist Alexander McClure later wrote, "No man ever entered the Presidency so profoundly and widely distrusted as Chester Alan Arthur, and no one ever retired ... more generally respected, alike by political friend and foe." He earned praise among contemporaries for his solid performance in office. The New York World summed up Arthur's presidency at his death in 1886: "No duty was neglected in his administration, and no adventurous project alarmed the nation." "I may be president of the United States, but my private life is nobody's damned business."
