Electric chair
The electric chair is a specialized device used for capital punishment through electrocution. The condemned is strapped to a custom wooden chair and electrocuted via electrodes attached to the head and leg. Alfred P. Southwick, a Buffalo, New York dentist, conceived this execution method in 1881. It was developed over the next decade as a more humane alternative to conventional executions, particularly hanging. First used in 1890, the electric chair became a symbol of capital punishment in the United States.
The electric chair was also used extensively in the Philippines. It was initially thought to cause death through cerebral damage, but it was scientifically established in 1899 that death primarily results from ventricular fibrillation and cardiac arrest. Originally a common method of capital punishment in the United States, its use has declined with the adoption of lethal injection which was perceived as more humane. While some states retain electrocution as a legal execution method, it is often a secondary option based on the condemned's preference. Exceptions include South Carolina, where it is the primary method, Louisiana, where the corrections secretary chooses the execution method, and Tennessee, where it can be used without prisoner input if lethal injection drugs are unavailable.
As of 2025, electrocution remains an option in states like Alabama, South Carolina, and Florida, where inmates may choose lethal injection instead. Arkansas, Kentucky, and Tennessee offer the electric chair to those sentenced before a certain date. Inmates not selecting this method or convicted after the specified date face lethal injection. Arkansas currently has no death row inmates sentenced before their select date. These three states also authorize electrocution as an alternative if lethal injection is deemed unavailable.
The electric chair remains an accepted alternative in Mississippi and Oklahoma if other execution methods are ruled unconstitutional at the time of execution. A significant shift occurred on February 8, 2008, when the Nebraska Supreme Court ruled electric chair execution as "cruel and unusual punishment" under the state constitution. This decision ended electric chair executions in Nebraska, the last state to rely solely on this method.
Background
Invention
In the late 1870s to early 1880s, the spread of arc lighting, a type of outdoor street lighting that required high voltages in the range of 3000–6000 volts, was followed by one story after another in newspapers about how the high voltages used were killing people, usually unwary linemen; it was a strange new phenomenon that seemed to instantaneously strike a victim dead without leaving a mark. One of these accidents, in Buffalo, New York, on August 7, 1881, led to the inception of the electric chair. That evening a drunken dock worker named George Lemuel Smith, looking for the thrill of a tingling sensation he had noticed when grabbing the guard rail in a Brush Electric Company arc lighting power house, managed to sneak his way back into the plant at night and grabbed the brush and ground of a large electric dynamo. He died instantly. The coroner who investigated the case brought it up that year at a local Buffalo scientific society. Another member attending that lecture, Alfred P. Southwick, a dentist who had a technical background, thought some application could be found for the curious phenomenon.Southwick joined physician George E. Fell and the head of the Buffalo ASPCA in a series of experiments electrocuting hundreds of stray dogs. They ran trials with the dog in water and out of water, and varied the electrode type and placement until they came up with a repeatable method to euthanize animals using electricity. Southwick went on in the early 1880s to advocate that this method be used as a more humane replacement for hanging in capital cases, coming to national attention when he published his ideas in scientific journals in 1882 and 1883. He worked out calculations based on the dog experiments, trying to develop a scaled-up method that would work on humans. Early on in his designs he adopted a modified version of the dental chair as a way to restrain the condemned, a device that from then on would be called the electric chair.
Gerry Commission
After a series of botched hangings in the United States, there was mounting criticism of that form of capital punishment and the death penalty in general. In 1886, newly elected New York State governor David B. Hill set up a three-member death penalty commission, which was chaired by the human rights advocate and reformer Elbridge Thomas Gerry and included New York lawyer and politician Matthew Hale and Southwick, to investigate a more humane means of execution.The commission members surveyed the history of execution and sent out a fact-finding questionnaire to government officials, lawyers, and medical experts all around the state asking for their opinion. A slight majority of respondents recommended hanging over electrocution, with a few instead recommending the abolition of capital punishment. The commission also contacted electrical experts, including Thomson-Houston Electric Company's Elihu Thomson and the inventor Thomas Edison. They also attended electrocutions of dogs by George Fell who had worked with Southwick in the early 1880s experiments. Fell was conducting further experiments, electrocuting anesthetized vivisected dogs trying to discern exactly how electricity killed a subject.
In 1888, the Commission recommended electrocution using Southwick's electric chair idea with metal conductors attached to the condemned person's head and feet. They further recommended that executions be handled by the state instead of the individual counties with three electric chairs set up at Auburn, Clinton, and Sing Sing prisons. A bill following these recommendations passed the legislature and was signed by Governor Hill on June 4, 1888, set to go into effect on January 1, 1889.
New York Medico-Legal Commission
The bill itself contained no details on the type or amount of electricity that should be used and the New York Medico-Legal Society, an informal society composed of doctors and lawyers, was given the task of determining these factors. In September 1888, a committee was formed and recommended 3000 volts, although the type of electricity, direct current or alternating current, was not determined, and since tests up to that point had been done on animals smaller than a human, some members were unsure that the lethality of AC had been conclusively proven.At this point, the state's efforts to design the electric chair became intermixed with what has come to be known as the war of the currents, a competition between Thomas Edison's direct current power system and George Westinghouse's alternating current based system. The two companies had been competing commercially since 1886 and a series of events had turned it into an all-out media war in 1888. The committee head, neurologist Frederick Peterson, enlisted the services of Harold P. Brown as a consultant. Brown had been on his own crusade against alternating current after the shoddy installation of pole-mounted AC arc lighting lines in New York City had caused several deaths in early 1888. Peterson had been an assistant at Brown's July 1888 public electrocution of dogs with AC at Columbia College, an attempt by Brown to prove AC was more deadly than DC. Technical assistance in these demonstrations was provided by Thomas Edison's West Orange laboratory and there grew to be some form of collusion between Edison Electric and Brown. Back at West Orange on December 5, 1888, Brown set up an experiment with members of the press, members of the Medico-Legal Society including Elbridge Gerry who was also chairman of the death penalty commission, and Thomas Edison looking on. Brown used alternating current for all of his tests on animals larger than a human, including 4 calves and a lame horse, all dispatched with 750 volts of AC. Based on these results the Medico-Legal Society recommended the use of 1000–1500 volts of alternating current for executions and newspapers noted the AC used was half the voltage used in the power lines over the streets of American cities. Westinghouse criticized these tests as a skewed self-serving demonstration designed to be a direct attack on alternating current and accused Brown of being in the employ of Edison.
At the request of death penalty commission chairman Gerry, Medico-Legal Society members; electrotherapy expert Alphonse David Rockwell, Carlos Frederick MacDonald, and Columbia College professor Louis H. Laudy, were given the task of working out the details of electrode placement. They again turned to Brown to supply the technical assistance. Brown asked Edison Electric Light to supply equipment for the tests and treasurer Francis S. Hastings tried to obtain a Westinghouse AC generator for the test but found none could be acquired. They ended up using Edison's West Orange laboratory for the animal tests they conducted in mid-March 1889. Superintendent of Prisons Austin E. Lathrop asked Brown to design the chair, but Brown turned down the offer. George Fell drew up the final designs for a simple oak chair and went against the Medico-Legal Society recommendations, changing the position of the electrodes to the head and the middle of the back. Brown did take on the job of finding the generators needed to power the chair. He managed to surreptitiously acquire three Westinghouse AC generators that were being decommissioned with the help of Edison and Westinghouse's chief AC rival, the Thomson-Houston Electric Company, a move that made sure that Westinghouse's equipment would be associated with the first execution. The electric chair was built by Edwin F. Davis, the first "state electrician" for the State of New York.
First execution
The first person in line to die under New York's new electrocution law was Joseph Chapleau, convicted for beating his neighbor to death with a sled stake, but his sentence was commuted to life imprisonment. The next person scheduled to be executed was William Kemmler, convicted of murdering his wife with a hatchet. An appeal on Kemmler's behalf was made to the New York Court of Appeals on the grounds that use of electricity as a means of execution constituted a "cruel and unusual punishment" and was thus contrary to the constitutions of the United States and the state of New York. On December 30, 1889, the writ of habeas corpus sworn out on Kemmler's behalf was denied by the court, with Judge Dwight writing in a lengthy ruling:We have no doubt that if the Legislature of this State should undertake to proscribe for any offense against its laws the punishment of burning at the stake, breaking at the wheel, etc., it would be the duty of the courts to pronounce upon such attempt the condemnation of the Constitution. The question now to be answered is whether the legislative act here assailed is subject to the same condemnation. Certainly, it is not so on its face, for, although the mode of death described is conceded to be unusual, there is no common knowledge or consent that it is cruel; it is a question of fact whether an electric current of sufficient intensity and skillfully applied will produce death without unnecessary suffering.
Kemmler was executed in New York's Auburn Prison on August 6, 1890; the "state electrician" was Edwin Davis. The first 17-second passage of 1,000 volts AC through Kemmler caused unconsciousness, but failed to stop his heart and breathing. The attending physicians, Edward Charles Spitzka and Carlos Frederick MacDonald, came forward to examine Kemmler. After confirming Kemmler was still alive, Spitzka reportedly called out, "Have the current turned on again, quick, no delay." The generator needed time to re-charge, however. In the second attempt, Kemmler received a 2,000 volt AC shock. Blood vessels under the skin ruptured and bled, and the areas around the electrodes singed; some witnesses reported that his body caught fire. The entire execution took about eight minutes. George Westinghouse later commented, "They would have done better using an axe", and The New York Times ran the headline "Far worse than hanging".
