A Short History of Murphy Beds
Murphy beds are named after William Lawrence Murphy (1876-1959), who was the first to apply for a patent on the system around 1900. He lived in a one-room apartment in San Francisco and wanted to be able to invite friends over—especially a certain opera singer. But being the gentleman he was, he wouldn't invite a woman into his bedroom. Since he only had one room, the bed took most of the space of the room.
In order to be able to turn his room into a living room, he had a blacksmith help him mount a mechanism that would make it possible to flip the bed into a closet. This way he was able to hide the bed and turn the bedroom into a living room. The trick worked and William later married the girl!
