  From Mobile Media Lab:

  The Hammond Novachord was invented in 1938, and uses over 160 vacuum tubes to generate 6 octaves of electronic sound. This purely electronic mechanism of tone generation is entirely different than the immensely popular Hammond Organ (released around one year earlier), which uses a series of motorized magnets to create its sounds. Only 1069 Novachords were ever made, before the Hammond Organ Company was conscripted into building radio transmitters and designing guided missile technology for WWII (after which they ceased production of the instrument, although the circuits were integrated into different Hammond instruments over the years, such as the Solovox and Chord Organ). The design of the Novachord, where all the notes on the keyboard could be played simultaneously, distinguished it sharply from the other purely electronic music instruments available at the time, such as the Theremin and Ondes Martenot, both of which are monophonic. This “chord-playing” feature, along with the mechanisms for sound filtering and shaping, grant the Novachord a claim as the first commercially available polyphonic synthesizer. Most of the 1000+ instruments that were built have been destroyed or lost.
