A monophonic electronic instrument (not an organ) patented as an musical entertainment device by the electrical engineer Larned A. Meacham of New Providence, New Jersey, on 6 March 1951 (no.2,544,466). The frequency of a single oscillator with a pitch range of approximately two and a half octaves was controlled by a ‘wobble arm’ moved by the player’s right hand around a calibrated quadrant dial; vibrato was also produced with the ‘wobble arm’. The left-hand controls included a push-button for the articulation of individual notes, which was combined with a volume control. The ‘wobble organ’ was normally used in a set of four, played by four performers seated around a table; in this case the frequency range of the instruments would usually be set to soprano, alto, tenor, and bass, and each would be given a different timbre by filtering the sawtooth wave produced by the oscillator. Meacham published directions for home assembly of the inexpensive, easy-to-use device. He held other patents in the field of electronic tone generation, amplification and detection, telephonic communication, semiconductors, etc....
