The Electric Chair Was Invented by a Dentist

In the late 1800s, New York wanted a more humane alternative to hanging, and the man they turned to had no background in criminal justice at all. Alfred Southwick was a dentist who spent his days pulling teeth in Buffalo, not designing machinery meant to end lives.

Southwick's idea came from something oddly mundane: he watched a drunk man touch a live generator terminal and die almost instantly, seemingly without pain. That single moment convinced him electricity could replace the rope, and he spent years lobbying officials to take the idea seriously.

To design the actual chair, Southwick borrowed heavily from his day job. Early prototypes looked suspiciously like dental chairs, complete with headrests and straps meant to keep a struggling patient still during a procedure.

The device also became an unlikely battlefield in the War of the Currents. Thomas Edison, pushing his direct current system, secretly funded the chair's development using rival Westinghouse's alternating current, hoping a gruesome execution would scare the public away from AC power entirely.

The first use of the chair in 1890, on convicted murderer William Kemmler, did not go the smooth, humane way Southwick promised. Witnesses described a horrifying scene that dragged on for several minutes, far from the instant death the dentist had envisioned.

Despite the disastrous debut, the chair stuck around for over a century, adopted by multiple states as their primary execution method. Its origins as a modified dental chair remained largely forgotten, buried under decades of legal and political history.

Southwick never saw himself as inventing an instrument of death, he genuinely believed he was solving a problem with compassion in mind. Instead, his dental office experiment became one of the most infamous pieces of equipment in American history.
