Ebeneezer Harker was a man who liked to play cards. His wife liked to go to parties, so she would steal one or two cards out of every deck he bought. He never had a full deck. It bothered him so much that he had a fit of apoplexy and died. His ghost haunted his former home, the old Harker house, until it was torn down.
Along with the ghosts of his wife and his uncle Jonathan Harker, Ebeneezer relocated to Goofy's house for a brief period of time, constantly counting his cards to see if they were all there. Eventually, Goofy and Mickey Mouse persuaded the three ghosts to live at the Haunted Mansion at Disneyland. Once he arrived, Ebeneezer quickly organized a card game with the ghosts of two old buccaneers who were loitering in the drawing room.
Ebeneezer Harker is featured in the story Spooky Tenants in the October 1969 Walt Disney Comics Digest.
