Laurens Hammond

Born 11 Jan 1895; died 1 Jul 1973 at age 78.American businessman and inventor whodevelopedthe electronic Hammond organ (patented 24 Apr 1934). Fascinated by science, Hammond patented his first invention, an automobile transmission, while barely a teenager. In 1909, he sold his idea for an inexpensive yet sensitive barometer, and in 1920, he sold his design for a “tickless”clock. In 1933, he stripped an old piano leaving only the keyboard action to use as a controller. He experimented with various different ways of generating sound until he found the one that sounded best - the tonewheel generator, with which he founded the Hammond Organ Company. During WW II, Laurens helped design guided missile controls with patents for bomb guidance.
