When Abraham Lincoln's son arrived back in Washington in April 1865, his parents invited him to go see Our American Cousin at Ford's Theater with them. The young Civil War officer was so exhausted after his journey that he begged off so he could get a good night's sleep. That night, of course, John Wilkes Booth shot Lincoln's father, and Robert Todd was with the celebrated president when he passed away the next morning.
By 1881, Lincoln's political lineage and prominence as a lawyer qualified him for a national office, and he became Secretary of War under the newly inaugurated James A. Garfield. That July, Lincoln was scheduled to travel to Elberon, New Jersey, by train with the President, but the trip never took off. Before Lincoln and Garfield's train could leave the station, Charles Guiteau shot Garfield, who died of complications from the wound two months later.
Oddly, that wasn't all for Lincoln, though. Two decades passed without a presidential assassination, but Lincoln's strange luck reared its head again in 1901. Lincoln traveled to Buffalo at the invitation of President William McKinley to attend the Pan-American Exposition. Although he arrived a bit late to the event, Lincoln was on his way to meet McKinley when anarchist Leon Czolgosz shot the president twice at close range.
Following these three bits of bad luck Lincoln refused to attend any presidential functions. He dryly noted that there was "a certain fatality about the presidential function when I am present."
