|President James A. Garfield|
He had served since March 4 of the same year. He had previously served nine terms in the House.
In the history of the presidency, four presidents have died from assassination. Another six were the subject of assassination attempts.
Here is a description of each assassination and attempt.
Garfield was close to President Lincoln's Treasury Secretary, Salmon Chase. He was an aggressive Republican, impatient with some of Lincoln's military leadership. He favored more civil rights for newly enfranchised black voters. During his brief term as President, he initiated civil service reform that was carried through by his successor.
