The electric chair was created by Alfred P. Southwick, a dentist and inventor from Buffalo, New York, in the early 1880s.

Who actually created it?

  • Alfred P. Southwick is widely credited as the inventor of the electric chair, after he proposed using electricity as a supposedly more humane alternative to hanging around 1881.
  • He developed the concept after learning about an accidental electrocution that killed a man almost instantly, which led him to experiment and publish on electrical execution.

How the electric chair was developed

  • Southwick first worked on electrocution methods using animals, and then adapted a modified dental-style chair into what became known as the electric chair.
  • In New York, commissions later refined his idea, and the first official electric chair was constructed and implemented for state executions in 1890.

Was Thomas Edison involved?

  • Although Edison did not invent the electric chair, he became involved in demonstrations and discussions around its use, partly as part of the “war of currents” between his direct current (DC) system and George Westinghouse’s alternating current (AC).
  • Edison’s lab provided technical help for animal electrocution experiments used to support AC-based execution, which helped associate Westinghouse’s AC with death, but the original idea and invention are still attributed to Southwick.
