The Insane Assassin of President James A. Garfield: Charles Julius Guiteau. Summary The tragic assassination of President James A. Garfield in the summer of 1881 was set in motion by Charles Julius Guiteau, a desperate office-seeker, who shot the President at a Washington train station. This account is a first-person investigation into Guiteau's life, tracing his trajectory from a difficult childhood in Illinois, through his failures with the Oneida Community, his fraudulent attempts at a legal career, and his rambling sermons, culminating in four months of relentless harassment that ended in the assassination. Through extensive research, including interviews with Guiteau's descendants, scrutiny of trial transcripts and medical records, and visits to locations central to his life, this narrative suggests Guiteau was a man whose personality flaws escalated into murderous delusions, likely fueled by neurosyphilis, a brain disease. Ironically, Garfield did not succumb to the bullet itself but to systemic infection over seventy-nine agonizing days, as doctors fatally probed the wound with unwashed hands, highlighting the need for antiseptic surgery. Despite dying on the gallows in the mistaken belief that he was a patriot, Guiteau's act inadvertently spurred three major reforms. His attempt to exploit the corrupt patronage system led to the Pendleton Civil Service Act, which dismantled it. His victim's medical tragedy forced American medicine to adopt antiseptic surgical practices. Furthermore, his trial exposed critical shortcomings in the legal handling of mental illness. The man who craved notoriety achieved it, ironically, by accidentally undermining all he stood for and ultimately fostering positive change in America.
