The electric chair, also known as the chair of death or the hot seat, is a machine used for capital punishment. This device is designed to execute a person by the means of an electric shock. The electric chair was first introduced in the late 19th century as an alternative to hanging, which was considered less humane. Synonyms for the electric chair include the death chair, the e-chair, and Old Sparky. While the use of the electric chair has decreased in recent years, it is still legally permissible in some states in the United States. Despite the different names, the electric chair remains a symbol of the ultimate form of punishment in the criminal justice system.
