Georges Jenny

Georges Marcel Charles Jenny (29 April 1913 – 23 September 1975) was a French musician, poet, and electronic instrument builder. His best-known invention was an electronic keyboard instrument called the Ondioline (sometimes referred to as the Jenny Ondioline). It is considered a forerunner of the synthesizer. The Ondioline is monophonic, yet it is capable of generating an array of sounds, and features a keyboard that produces a natural-sounding vibrato via side-to-side finger movements when keys are depressed.
