Leonard M. Greene, 88; aviation safety pioneer held 200-plus patents
Leonard M. Greene, 88, an inventor and pioneer in aviation safety who developed an instrument that would warn a pilot that a plane was about to stall, died Nov. 30 of cancer at a hospital in White Plains, N.Y.
According to the New York Times obituary of Greene, the device he developed gives an audible alert to a pilot when an aircraft is in danger of not having the required lift to maintain altitude.
A native of New York City, Greene earned bachelor’s and master’s degrees at City College of New York. He was an aerodynamicist and engineering test pilot for Grumman before founding Safe Flight Instrument in White Plains, the Times obituary reported.
Greene, who held more than 200 patents, was also a co-founder of the Corporate Angel Network, which arranges free rides on corporate aircraft for cancer patients.
