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. He served as a member of the Ohio State Senate from 1859 to 1861. He was forced to return home, where his wife nursed him back to health. While he was home, Garfield's friends worked to gain him the Republican nomination for Congress, but he refused to campaign with the delegates. He returned to military duty that autumn and went to Washington to await his next assignment. During this period of idleness, a rumor of an extramarital affair caused friction in the Garfields' marriage until Lucretia eventually chose to overlook it.
