The first person to die in the gas chamber was Gee Jon.
He was convicted of assassinating a member of a rival Chinese tong and died in a gas chamber in Nevada State Prison in Carson City on February 8, 1924.
The idea of the gas chamber was introduced by Major D. A. Turner of the U.S. Army Medical Corps as the “quickest and most humane method of putting a human to death.”
The process, which used hydrocyanic gas, took six minutes.
