The electric chair was indeed invented by a dentist, Dr. Alfred P. Southwick, a former steam-boat engineer and dental educator. Southwick's invention was based on the dentist's chair. In the 1880s, Southwick witnessed an accidental death by electrocution and concluded that electrocution was a quick and painless way to die. He believed that it could be a more humane form of capital punishment compared to hanging, beheading, and other methods. Southwick's advocacy led to the first law allowing electrical execution, which went into effect in New York State on January 1, 1889. The first person to die in the electric chair was William Kemmler in 1890, and the debut caused outrage as two shocks were needed to cause death. Despite this, the use of the electric chair was soon adopted across many states.

Dr Alfred P. Southwick, a dentist, steam-boat engineer and inventor, is credited with the invention of the electric chair
Southwick modified a dentist's chair and began experimenting on animals. He served on the New York State Commission on Human Execution, where he advocated for the use of his invention as a more humane method of capital punishment. In 1886, the newly elected New York State governor, David B. Hill, set up a three-member death penalty commission to find a more humane form of execution. Southwick was one of the members of this commission. The committee explored various forms of execution and, in 1888, recommended electrocution using Southwick's electric-chair idea.
On January 1, 1889, the first law allowing the use of electrocution went into effect in New York State. On August 6, 1890, William Kemmler, a convicted murderer, was the first person to be executed by the electric chair. The execution was not without issues, as a second jolt of electricity was required, and the event caused outrage among the public and press. Despite this, Southwick continued to advocate for the use of the electric chair as a more humane alternative to other methods of capital punishment.
Southwick's legacy is forever linked to his invention of the electric chair, despite his initial intentions of easing human suffering.

Southwick's research into electrocution as a form of capital punishment was inspired by an accidental death in 1881
In 1881, Dr. Alfred P. Southwick, a dentist, inventor, and former steamboat engineer, read about a widely reported story of a Buffalo dockworker who accidentally died by electrocution. The man had died almost instantly and seemingly without pain. At that time, capital punishment was common, and hanging was the usual method of execution, which often resulted in botched attempts. Southwick's research into electrocution as a form of capital punishment was inspired by this accidental death, and he concluded that electrocution could be a more humane alternative.
Southwick's initial interest in electricity stemmed from his desire to alleviate the pain experienced by his dental patients. He began to explore the possibility of using low-voltage electricity to reduce their discomfort. However, after the accidental death in 1881, his research took a different turn. He modified a dentist's chair and started experimenting on animals. Southwick lobbied for electrocution as a more humane form of capital punishment, and his position as a dentist played a crucial role in the development of the electric chair.
In 1886, the newly elected New York State Governor, David B. Hill, established a three-member death penalty commission to find a more humane form of execution. Southwick was appointed to this commission, along with human rights advocate Elbridge Thomas Gerry and New York lawyer Matthew Hale. The commission explored various forms of execution, and in 1888, they recommended electrocution using Southwick's electric chair idea.
Southwick's advocacy for electrocution as a humane alternative to hanging was based on his observation of the dockworker's death. He believed that electrocution was quick and seemingly painless. As a result of his efforts, the first law allowing the use of electrocution went into effect in New York State on January 1, 1889. Southwick successfully promoted the passage of laws mandating electrical executions in New York and approximately 20 other states.

Southwick modified a dentist's chair and experimented on animals
Dr Alfred P. Southwick, a dentist, former steam-boat engineer, and dental educator, is credited with the invention of the electric chair. Southwick's interest in easing the pain of his dental patients and his engineering experience led him to experiment with low-voltage electricity. In 1881, he read about a dockworker in Buffalo, New York, who accidentally died by electrocution. The worker was reported to have died instantly and without pain, which sparked Southwick's idea to use electricity as a more humane form of capital punishment compared to the commonly used method of hanging, which often resulted in botched executions.
Southwick modified a dentist's chair and began experimenting on animals, specifically stray dogs. He served on the New York State Commission on Human Execution, where he advocated for the use of his invention as a more humane method of capital punishment. In 1886, the newly elected New York State governor, David B. Hill, formed a three-member death penalty commission that included Southwick to find a more humane form of execution. The commission explored various forms of execution and recommended electrocution using Southwick's electric chair idea.
Southwick's design for the electric chair involved a chair with metal conductors attached to the condemned person's head and feet. On January 1, 1889, the first law allowing the use of electrocution went into effect in New York State. On August 6, 1890, the electric chair was first used to execute William Kemmler, who had murdered his mistress. However, the execution was botched, as Kemmler did not die from the initial surge of electricity and required a second jolt. This caused outrage and criticism from the public and the press. Despite this, Southwick continued to advocate for the use of electrical execution as a more humane form of capital punishment, and it was soon adopted across many states.

The first use of the electric chair in 1890 was botched, requiring two jolts of electricity to kill William Kemmler
The electric chair was conceived by dentist Alfred P. Southwick, who believed that electrocution was a more humane alternative to hanging, beheading, and other common methods of capital punishment. On August 6, 1890, William Kemmler, convicted of murdering his common-law wife, became the first person to be executed by the electric chair.
Kemmler's execution was not without complications, however. After an initial surge of electricity, Kemmler did not die immediately, and a second jolt was required to cause his death. The execution was described as a bungled spectacle that left those who witnessed it stunned. The press and the public criticized the event as "disgusting, sickening, and inhuman."
During the execution, the initial surge of electricity did not immediately kill Kemmler. A doctor prematurely declared him dead, but Kemmler then let out a deep groan, prompting witnesses to scream, "Turn on the current!" The execution chamber filled with the smell of burning flesh, causing two witnesses to faint and several others to experience severe nausea.
The electric chair's invention was an attempt to find a more humane method of execution, but Kemmler's death in 1890 showed that this new method had its own issues. Despite the complications, supporters of electrocution, including Thomas Edison, continued to advocate for it as a quick, effective, painless, and humane alternative to other forms of capital punishment.
