Emulating a disembodied voice, the theremin s potential was soon realized in America s burgeoning film industry, where it was regularly employed to accompany the supernatural and extraterrestrial a flying saucer, a ray gun, an alien creature, and all sorts of other phenomena in black-and-white B movies of the 1950s. Beyond that niche, the theremin also found a place albeit marginally in classical and popular music.
Robert Moog was the first to mass-produce the theremin, which then inspired him to create his now iconic line of synthesizers. Moog died in 2005, but his company, Moog Music, continues producing synthesizers and theremins to this day.
