“Pep, The Cat-Murdering Dog” was a black Labrador Retriever admitted to Eastern State Penitentiary on August 12, 1924. Prison folklore tells us that Pennsylvania Governor Gifford Pinchot used his executive powers to sentence Pep to Life Without Parole for killing his wife’s cherished cat. Prison records support this story: Pep’s inmate number (C-2559) is skipped in prison intake logs and inmate records. The Governor told a different story. He said Pep had been sent to Eastern to act as a mascot for the prisoners. He and the Warden, Herbert “Hard-Boiled” Smith, were friends. Pep was much loved, and lived among the inmates at Eastern State for about a decade. While the truth may never be known, in photographs Pep, with his head down and ears back, looks GUILTY.
