He was an actor. Actors in those days rarely had permanent homes because the shows travelled town to town. So he was well known in the theater. It was no surprise to see him wandering about. He was there picking up his mail when he found out Lincoln would be there that night. So he snuck in later and wedged the door closed with a broken music stand left lying around....the guard - only one and before the advent of Secret Service Agents - had been instructed by the president to have a seat and enjoy the show.
BESIDES Mili Steele-Hollenbeck. Lincoln didn't like to have security by him and there had never been an assassination to a president before!!
Different times. Secret Service was actually created (to counteract counterfeiting) the same day Lincoln was shot.
He snuck in. He showed up after the performance started and nobody saw him walk-in. The Bodyguard had gone to a bar to drink.
