President Garfield was shot by an assassin in July 1881 and lingered for 80 days before dying in September. The initial wound was minor but doctors probing for the bullet with unsterilized instruments turned it into a large, contaminated wound. As the wound worsened under the doctors' ministrations, Garfield developed a fever and his condition declined. He died from complications including a heart attack, turning what would likely have been a minor injury into a fatal case due to the medical treatment at the time.
