This is a film taken of the execution of Topsy, an elephant employed to help build Luna Park on Coney Island. She had killed three men, including a drunken spectator who fed her a cigarette. Cyanide-laced carrots fed to her by park officials failed, and the ASPCA forbade a hanging. Thomas Edison, meanwhile, had been publicly killing dogs and cats with AC power to show that his DC power was more effective and less dangerous. Edison performed the execution of Topsy and captured it on film, though the brief short shows only the event, and not the background behind it. It makes a disturbing sight, particularly embedded in Errol Morris's Mr. Death: The Rise and Fall of Fred A. Leuchter, Jr. (1999).
