The electric chair was first adopted in 1888 in New York as a quicker and more humane alternative to hanging. The first electric chair was built in 1888, and it executed William Kemmler in 1890. The electric chair 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. The process of execution involves shaving the prisoner's head and legs, strapping them to a chair, and attaching electrodes to their legs and a cap with a saltwater-soaked sponge to their head. The executioner then pulls a handle to connect the power supply, delivering a jolt of between 500 and 2500 volts of electricity for about 30 seconds. This process is repeated until the prisoner is dead, as indicated by a doctor.

What You'll Learn

The electric chair was first adopted in 1888
The adoption of the electric chair in 1888 was influenced by the \"war of the currents\" between Thomas Edison's direct current power system and George Westinghouse's alternating current system. Harold P. Brown, a consultant for the committee head neurologist Frederick Peterson, had been crusading against alternating current after shoddy installations of pole-mounted AC arc lighting lines in New York City caused several deaths in 1888. Brown publicly electrocuted dogs with AC at Columbia College in July 1888 to prove that AC was more deadly than DC.
The first use of the electric chair in 1890 was a highly publicized and grotesque execution. Kemmler's face was bloody, his hair and skin scorched, and the death chamber was described as having an "unbearable stench." Despite this, other states soon adopted the electric chair as an execution method. By 1949, it was the method of execution in 26 states.
Today, the electric chair is no longer the sole method of execution in any state. The use of the electric chair has declined with the adoption of lethal injection, which is perceived as more humane. However, some states still allow inmates to choose between electrocution and lethal injection, and it remains an option in states like Alabama, South Carolina, and Florida.

The prisoner is strapped to a chair
The executioner pulls a handle to connect the power supply, sending a jolt of between 500 and 2500 volts through the body for about 30 seconds. The current is then turned off, and the body relaxes. Doctors wait for the body to cool down before checking for a heartbeat. If the prisoner's heart is still beating, another jolt is applied. This process continues until the prisoner is dead.
The electric chair was first adopted in 1888 in New York as a more humane alternative to hanging. New York built the first electric chair in 1888 and executed William Kemmler in 1890. Soon, other states followed suit. By 1949, electrocution was the method of execution in 26 states. However, the highly publicized and botched execution of Kemmler raised questions about the humanity of the method.
Today, electrocution is not the sole method of execution in any state. In 2008, the Nebraska Supreme Court ruled that execution by electric chair was "'cruel and unusual punishment'", and it was ruled unconstitutional. Lethal injection is now the most widely used method of execution in the United States. However, some states still allow electrocution as a secondary option, or if lethal injection is unavailable or deemed unconstitutional.

A metal skullcap electrode is attached to the scalp
The electric chair was initially believed to cause death through cerebral damage. However, it was later discovered that death occurs primarily due to ventricular fibrillation and cardiac arrest.
The process of preparing a prisoner for execution by the electric chair involves shaving their head and legs before they are seated in the chair. Their arms and legs are then strapped with leather belts.
A metal skullcap-shaped electrode is attached to the scalp and forehead over a sponge moistened with saline solution. The saline solution is crucial, as too much or too little moisture can affect the electric current. The electrode is coated with a conductive paste or gel to ensure good mechanical and electrical contact with the scalp.
The skullcap electrode plays a central role in delivering the electric current that causes ventricular fibrillation and cardiac arrest. This current is intended to induce immediate unconsciousness, followed by the cessation of heart function.

The prisoner is given a jolt of 500-2000 volts
The electric chair was first adopted in 1888 in New York as a quicker and more humane alternative to hanging. The first electric chair was built in 1888, and the first execution using this method was carried out in 1890.
For execution by the electric chair, the prisoner's head and legs are shaved, and they are seated in the chair. Their arms and legs are then strapped with belts, and a cap with a saltwater-soaked sponge is strapped to their head. Electrodes are attached to the prisoner's head and legs. The prisoner is then blindfolded.
The prisoner is then given a jolt of 500-2000 volts, which lasts for about 30 seconds. The voltage causes a powerful electric shock, which is intended to cause immediate unconsciousness, ventricular fibrillation, and eventual cardiac arrest. The current surges through the body and is then turned off, at which time the body relaxes.
After the initial jolt, the doctors wait a few seconds for the body to cool down and then check to see if the prisoner's heart is still beating. If it is, another jolt is applied. This process continues until the prisoner is dead.

Lethal damage to internal organs
The electric chair was initially thought to cause death through cerebral damage. However, it was scientifically established in 1899 that death primarily occurs due to ventricular fibrillation and cardiac arrest.
The process of execution by the electric chair involves shaving the condemned inmate's head and legs and seating them in the chair. Their arms and legs are then tightly strapped with leather belts. A cap with a saltwater-soaked sponge is secured to the head, and electrodes are attached to the legs. The inmate may be blindfolded or have a bag placed over their head.
The first electric shock, ranging from 2,000 to 2,5000 volts, is intended to cause immediate unconsciousness, ventricular fibrillation, and eventual cardiac arrest. The second shock, which is less powerful at 500 to 1,500 volts, is designed to induce lethal damage to the vital organs. This lower-voltage shock follows the initial high-voltage shock to ensure death.
The electric chair causes lethal damage to internal organs by passing alternating current through the individual's body, resulting in multiple organ failure. The current surges through the body, causing the vital organs to shut down. The process may be repeated if the prisoner is still alive, as the doctor will check for any signs of life after the initial cycle.
