Laurens Hammond

Died 1 Jul 1973 at age 78 (born 11 Jan 1895).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.
