Robert Lincoln, Abe’s son, was present when this happened. I believe it was after this that he avoided being in the presence of a President. I think he thought himself a jinx of sorts.
Robert Todd 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.
