The electric chair was invented in the 1880s by New York engineer and dentist Alfred P. Southwick as a more humane alternative to hanging. The device was first used for execution in 1890, when William Kemmler became the first person to be electrocuted. The electric chair was originally powered by Alternating Current (AC), which was championed by inventor George Westinghouse. However, Thomas Edison, who preferred Direct Current (DC), secretly arranged for the first electric chair to be built with AC power to scare people into thinking it was more dangerous.

What You'll Learn

The electric chair was conceived in 1881
Southwick's idea was to use electricity as a replacement for hanging in capital cases. He worked out calculations based on his experiments with dogs, trying to develop a method that would work on humans. He adopted a modified version of the dental chair as a way to restrain the condemned, a device that would become known as the electric chair.
Southwick's idea gained national attention when he published his ideas in scientific journals in 1882 and 1883. In 1886, the New York State Government established a commission to study alternative forms of capital punishment. Hanging was the primary method of carrying out the death penalty, but it was considered too slow and painful. A slight majority of respondents to the commission's questionnaire recommended hanging over electrocution, with a few recommending the abolition of capital punishment altogether.
Despite the mixed response, the electric chair was developed over the next decade, and in 1890, it was used for the first time. The execution of murderer William Kemmler caused outrage as two shocks were required to kill him. However, the idea was soon adopted across many states, and the electric chair became a symbol of capital punishment in the United States.

It was invented in the 1880s
The electric chair was invented in the 1880s, with the idea for the execution method being conceived in 1881 by a Buffalo, New York dentist named Alfred P. Southwick. Southwick's idea came about after a drunken dock worker named George Lemuel Smith was killed by high-voltage arc lighting in Buffalo, New York, on August 7, 1881.
In the late 1880s, employees at Thomas Alva Edison's works in West Orange, New Jersey, invented the electric chair. Edison wanted to see capital punishment abolished in the US but thought electrocution would be quicker and less painful than hanging. He and his team experimented on living creatures, including dogs, cats, pigs, calves, and even an adult horse, to determine a reliable electrical charge to dispatch a human.
In 1886, the governor of New York State, David B. Hill, set up a three-member death penalty commission to investigate a more humane means of execution. The commission contacted electrical experts, including Elihu Thomson of the Thomson-Houston Electric Company and inventor Thomas Edison, who recommended high-voltage AC connected to the head and spine.
In the early 1880s, Southwick advocated for his method to be used as a more humane replacement for hanging in capital cases, gaining national attention when he published his ideas in scientific journals in 1882 and 1883. He designed and patented a device with straps and electrical wires, which he successfully tested on animals. Southwick's invention resembled a dentist's chair, and he adopted a modified version of this design to restrain the condemned.
In 1888, the Edison research facility hired inventor Harold Brown, who, along with his assistant, Doctor Fred Peterson, began designing an electric chair for Edison. They experimented with DC voltage, demonstrating that it did not kill lab animals, and then tested AC voltage to show that it caused swift death. In 1888, the electric chair replaced hanging as a means of execution, and in 1889, New York State adopted it as a more humane method of capital punishment. The first execution by electric chair was carried out in 1890 when a street pedlar named William Kemmler was put to death.

New York was the first state to introduce execution by electric chair
The electric chair was conceived in 1881 by Alfred P. Southwick, a Buffalo, New York-based dentist. Southwick's idea for the electric chair was inspired by an accident in Buffalo, New York, on August 7, 1881, when a drunken dock worker accidentally killed himself by grabbing a generator at a Brush Electric Company arc lighting power house.
Southwick began experimenting on animals and advocated for the use of electricity as a more humane alternative to hanging for capital punishment. In 1882 and 1883, he published his ideas in scientific journals, and his concept gained national attention.
In 1886, the New York State governor, David B. Hill, set up a three-member death penalty commission to investigate a more humane means of execution. The commission surveyed the history of execution and sought opinions from government officials, lawyers, and medical experts. A slight majority of respondents recommended hanging over electrocution, while a few recommended abolishing capital punishment altogether.
On June 4, 1888, the New York Legislature passed a law establishing electrocution as the state's official method of execution. However, the specific design of the electric chair was left to a committee, which selected a design using AC voltage.
On January 1, 1889, New York became the first state to introduce execution by electric chair as the world's first electrical execution law went into full effect. The first person to be executed by electric chair was William Kemmler on August 6, 1890. The electric chair soon became a symbol of capital punishment in the United States and was also used extensively in the Philippines.

The first execution was botched
The electric chair was first used for execution in the United States in the late 19th century, and it remained a common method of capital punishment into the 20th century. The first attempt at an electric chair execution, however, was botched and brought to light the issues with this form of execution.
On August 6, 1890, William Kemmler, a convicted murderer, became the first person to be executed by electric chair. The execution took place at Auburn Prison in New York and was witnessed by a small group of officials and journalists. Kemmler was strapped into the newly invented electric chair, designed to quickly and humanely end his life. However, the procedure did not go as planned. The voltage was too low to cause immediate death, and Kemmler remained alive after the first jolt of electricity. The current had caused his body to catch fire, and the executioners had to let his body cool down before they could apply a second jolt of electricity. This time, a higher voltage was used, and Kemmler was successfully executed.
The botched execution caused a media frenzy, with newspapers reporting the gory details and questioning the humanity of the electric chair. Despite this, the electric chair was soon adopted by other states as a preferred method of execution, and it became a fixture in the American justice system for decades to come. This first attempt highlighted the potential issues with this form of capital punishment and brought to light the challenges of ensuring a quick and painless death.
The electric chair was intended to be a more humane method of execution, a swift and scientific alternative to hanging. However, as Kemmler's case demonstrated, the procedure could go horribly wrong. The botched execution raised concerns about the electric chair's effectiveness and brought attention to the potential for human error and equipment failure. It also sparked debates about the ethics of state-sanctioned death and the responsibility of those carrying out the execution.
Kemmler's execution marked a turning point in the history of capital punishment, as it brought to light the complexities and challenges of implementing the death penalty in a seemingly modern and progressive society. While the electric chair would continue to be used for decades, this first attempt highlighted the potential for error and the need for extreme caution and precision in carrying out state-sanctioned executions.

The electric chair was declared cruel and unusual punishment in 2008
The electric chair was conceived in 1881 by Alfred P. Southwick, a dentist from Buffalo, New York. Southwick's idea was to use electricity as a more humane alternative to hanging for executions. The electric chair was first used in 1890, becoming a symbol of capital punishment in the United States.
Despite its long history as a method of execution, the electric chair has been criticised for being a cruel and unusual form of punishment. On February 8, 2008, the Nebraska Supreme Court ruled that the use of the electric chair violated the state constitution's ban on cruel and unusual punishment. This decision marked a significant shift, as Nebraska was the last state to rely solely on this method of execution.
The ruling by the Nebraska Supreme Court was based on the argument that electrocution inflicts intense pain and agonising suffering on the condemned. This decision was an important step towards eliminating inherently inhumane executions in the United States. Human Rights Watch, an organisation that defends human rights in nearly 100 countries, applauded the ruling, stating that it abolished the "barbaric practice of electrocutions" in Nebraska.
The electric chair's decline in use as a method of execution can also be attributed to the adoption of lethal injection, which is perceived as a more humane alternative. Lethal injection has gradually replaced the electric chair in many states, with the most recent U.S. states being Indiana in 1995 and Tennessee after a certain date. However, as of 2025, electrocution remains an option in Alabama, South Carolina, and Florida, where inmates may choose between electrocution and lethal injection.
