James Abram Garfield (November 19, 1831 – September 19, 1881) was the 20th president of the United States, serving from March 4, 1881, until his death by assassination six and a half months later. He is the only sitting member of the United States House of Representatives to be elected to the presidency.Garfield entered politics as a Republican in 1857. The fact that the new Congress would not hold its first regular session until December 1863 allowed him to continue his war service for a time.
