A twenty-three-year-old Union Army soldier and doctor, Leale attended the play at Ford’s after hearing that General Grant would attend. He was the first doctor to reach Lincoln after the president was shot. He at first assumed the president was stabbed, but then ascertained that he had been shot in the head and would not recover. He supervised the transportation of the president across the street to the Petersen house and stayed with him until his death, at one point trying to remove the bullet from within the dying man’s skull with the Nelaton probe.
