First used by New York State in 1890, it was used throughout the 20th century to execute hundreds and is still an option in eight states. Since 1976, 158 inmates have been executed by electrocution. It was considered humane on its introduction but resulted in many horrific executions over the years. (AP Photo, File)
William Kemmler, who had been convicted of murder and sentenced to death, was the first person executed by electric chair. The execution took place in Auburn, N.Y.
The electricity was turned on for 17 seconds, but it was not enough to kill the condemned man. Another shock lasting considerably longer was administered until witnesses could smell the body burning and there was no doubt the man was dead.
Many condemned this form of execution after witnessing it.
