Leonard Greene

Leonard Michael Greene was an American inventor and aerodynamics engineer who held more than 200 patents, many of which are aviationrelated. He is most well known for his contributions to aviation technology, including his invention, the Aircraft Stall Warning device, which warns pilots when a deadly aerodynamic stall is imminent. To build the device, Greene established the Safe Flight Instrument Corporation in 1946.

Leonard M. Greene was born in New York City on June 8, 1918. Max Greene, his chemist father, and Lyn Furman Greene, his artist mother, encouraged their son to create his own toys. His parents made him a gift of their old stove, which he could take apart. Greene experienced poverty as a youth during the Depression and never forgot it.
