The term "Droid" was first used in the science fiction story "Robots of the World! Arise!" by Mari Wolf, published in If: Worlds of Science Fiction in July 1952: Jack shook his head. "It's crazy. They're swarming all over Carron City. They're stopping robots in the streets--household Robs, commercial Droids, all of them." -Mari Wolf, "Robots of the World! Arise!"
