The Teplitz Family Ghosts are the ghosts of Professor Harold Teplitz's wife and parents.
For two years, the Teplitz Family Ghosts appeared to Harold after his death and tried in vain to urge him to cross over with them to the afterlife. After a plan was hatched to neutralize the Ghostbusters, Harold manipulated Egon Spengler into helping get rid of his family and advance his plans at the same time. Egon came to the Teplitz Townhouse on late Tuesday afternoon and implored Harold to admit he was a ghost and let his family escort him. Harold pretended to. While his family crossed over, Harold did not.
