Charles J. Guiteau
Charles Julius Guiteau ( ghih-TOH; September 8, 1841 – June 30, 1882) was an American office seeker who assassinated the 20th President of the United States, James A. Garfield, in 1881. A failed lawyer suffering from mental illness, Guiteau delusionally believed he had played a major role in Garfield's election victory, for which he should have been rewarded with a consulship.
