Electrocution

Lore & Background

The earliest recorded injury from human-made electricity occurred in 1746 in the Netherlands, when Pieter van Musschenbroek's lab assistant Andreas Cuneus received an extreme shock while working with a Leyden jar. By the mid-19th century, high-voltage electrical systems powered arc lighting for theaters and lighthouses, leading to the first recorded accidental death in 1879 when a stage carpenter in Lyon, France, touched a 250-volt wire. After 1880, arc light street lighting systems running above 3,000 volts caused many deaths, a new phenomenon that seemed to kill instantaneously without leaving marks.

This phenomenon led to execution by electricity in the electric chair in the early 1890s as an official method of capital punishment in New York, thought to be more humane than hanging. After an 1881 death in Buffalo, New York, caused by a high-voltage arc lighting system, dentist Alfred P. Southwick sought to develop this into a way to execute condemned criminals, basing his device on the dental chair. Over the next nine years, Southwick promoted the idea, the New York state Gerry commission recommended execution by electricity, a law was passed on June 4, 1888, taking effect January 2, 1889, and a further committee finalized details.

The adoption of the electric chair became mixed up in the 'war of currents' between Thomas Edison's direct current system and George Westinghouse's alternating current system. In 1889, anti-AC activist Harold P. Brown became a consultant to the committee and pushed, with assistance from Edison Electric and the Thomson-Houston Electric Company, for adoption of alternating current to power the chair, aiming to portray AC as a 'executioners' current'.

Electrocution represents a significant intersection of technological progress, public safety, and capital punishment. The term itself emerged from the need to describe a new form of execution in 1889, with tabloid newspapers settling on 'electrocution' as a portmanteau of 'electro' and 'execution'. Other proposed terms included 'Westinghoused', 'Gerrycide', and 'Browned', while Thomas Edison preferred 'dynamort', 'ampermort', and 'electromort'. The New York Times opposed the word, calling it pushed by 'pretentious ignoramuses'. Medically, electrocution causes about 1000 fatalities annually in the United States, with around 400 from high-voltage sources and 50 to 300 from lightning. The mechanism of cardiac arrest is typically ventricular fibrillation, and the severity depends on current amount and duration, not merely voltage. The historical adoption of the electric chair was influenced by the commercial rivalry between Edison and Westinghouse, with alternating current deliberately chosen to stigmatize it as dangerous. This legacy continues to inform both electrical safety standards and debates over capital punishment methods.

Did You Know?

• The word 'electrocution' was coined in 1889 in the US just before the first use of the electric chair.
• Thomas Edison preferred the words 'dynamort', 'ampermort', and 'electromort' over 'electrocution'.
• In Nazi concentration camps, prisoners commonly committed suicide by throwing themselves at electric fences, known as 'going to the wire'.

The First Sparks: Early Encounters with Lethal Current

Humanity's first documented encounter with dangerous artificial electricity occurred in 1746 in the Netherlands, when Andreas Cuneus, a laboratory assistant to Pieter van Musschenbroek, suffered an extreme shock while handling a leyden jar. For over a century, such incidents remained isolated curiosities. That changed in the mid-nineteenth century, when high-voltage electrical systems were deployed to power arc lighting for theatrical stages and lighthouses. The first recorded accidental electrocution followed in 1879, when a stage carpenter in Lyon, France, made contact with a 250-volt wire. The situation escalated dramatically after 1880, as arc-light-based street lighting networks—operating at voltages exceeding 3,000—spread across cities. Workers and passersby who touched these lines died almost instantly, a baffling new phenomenon that left no visible wound on the victim. This wave of mysterious, markless deaths transformed public perception of electricity from a scientific marvel into a genuine hazard, setting the stage for both industrial safety concerns and, paradoxically, the invention of the electric chair.

The Chair and the Current War

Following an 1881 electrocution in Buffalo, New York, caused by a high-voltage arc lighting system, dentist Alfred P. Southwick began advocating for electricity as a method of capital punishment, designing his apparatus around the familiar form of a dental chair. Over the next nine years, his campaign gained momentum: the New York state Gerry commission, which included Southwick itself, formally recommended electrical execution; a law signed on June 4, 1888, made it the state's official method effective January 2, 1889; and a committee of physicians and attorneys worked out the technical details. Yet the adoption of the chair became entangled in the bitter commercial rivalry between Thomas Edison's direct-current system and George Westinghouse's alternating-current system. Anti-AC activist Harold P. Brown, serving as a committee consultant, pushed for alternating current to power the device, with the assistance—and at times the collusion—of Edison Electric and Westinghouse's chief rival, the Thomson-Houston Electric Company. Their goal was to brand AC as a public menace, coining the phrase 'executioners' current' to poison public confidence in the technology.

Naming the Unnameable

In May 1889, New York sentenced William Kemmler, a street merchant and convicted murderer, to die by the state's newly adopted electrical method. Tabloid newspapers scrambling to label this unprecedented form of death settled on 'electrocution,' a portmanteau blending 'electro' and 'execution.' The choice was far from unanimous. The New York Times editorial page noted competing suggestions: 'Westinghoused,' after the AC equipment that would power the chair; 'Gerrycide,' named for Elbridge Thomas Gerry, who headed the commission that proposed the method; and 'Browned,' referencing anti-AC advocate Harold P. Brown. Edison himself favored the more clinical-sounding dynamort, ampermort, and electromort. The Times despised 'electrocution,' dismissing it as a term pushed by 'pretentious ignoramuses.' Originally the word applied exclusively to judicial execution by electricity. Because no existing English term described accidental or non-judicial deaths from commercial current, 'electrocution' gradually absorbed that broader meaning, becoming the universal descriptor for all electrical fatalities.

The Physiology of a Lethal Current

Electrocution claims roughly one thousand lives in the United States annually, with about four hundred of those deaths traced to high-voltage sources and between fifty and three hundred resulting from lightning strikes. The mechanism of death is well understood: a current passing through the chest triggers ventricular fibrillation rather than asystole, causing the heart to quiver uselessly and preventing effective blood circulation. A shock requires a voltage source and at least two points of contact on the body; the severity depends on the magnitude of current and the duration of flow, not voltage alone, though high voltage is necessary to overcome the relatively high resistance of dry skin. Currents as low as 30 milliamps of AC or 300 to 500 milliamps of DC can induce fibrillation, while 70 to 700 milliamps typically produce it—reversible with a defibrillator but nearly always fatal without intervention. Currents exceeding one ampere cause irreversible burns and cellular destruction. If the path traverses the brain or spinal cord, death may instead result from respiratory paralysis or interference with the nervous system's control of breathing.
