What president was assassinated by an office seeker?

James A. Garfield (1831-1881) was shot by Charles Guiteau, a frustrated would-be diplomat, on Saturday, July 2, 1881, less than four months after Garfield took office. Garfield died 11 weeks later, on Friday, September 19, 1881. Guiteau thought he deserved an appointment as ambassador to France and when refused ,he made such a nuisance of himself at the White House that eventually he was told not to come back again. He then decided to shoot the President.
