In 1833, the first U.S. patent for a fireproof safe was issued to Charles A. Gaylor of New York City, as a “fire-proof iron chest.” He made it from two chests, one within the other, with a space between to “inclose air of any non-conductor of heat.” Gaylor called his product the Salamander Safe, after the mythical salamander, an animal having the power to endure fire without harm.
