The museum stands on the former site of the Baltimore and Potomac Railroad station, where in 1881 a disgruntled office seeker, Charles Guiteau, shot President James Garfield (see James A. Garfield assassination). As anticipated by Mellon, the creation of the National Gallery encouraged the donation of other substantial art collections by a number of private donors.

Charles J. Guiteau Supreme Court into hearing his court appeal. He was hanged on June 30, 1882, in the District of Columbia, just two days before the first anniversary of the shooting. While being led to his execution, Guiteau was said to have continued to smile and wave at spectators and reporters, happy to be at the center of attention to the very end. He notoriously danced his way to the gallows and shook hands with his executioner. On the scaffold, as a last request, he recited a poem called "I am Going to the Lordy", which he had written during his incarceration.
