Merle Antony Tuve

Died 20 May 1982 at age 80 (born 27 Jun 1901).American research physicist and geophysicist who (with Gregory Breit) made the first use pulsed radio waves to explore the ionosphere. He devised the necessary detecting equipment to measure the time between receiving a direct radio pulse and a second pulse reflected from the ionosphere. The observations he made provided the theoretical foundation for the development of radar. Tuve, with Lawrence R. Hafstad and Norman P. Heydenburg, made the first and definitive measurements of the nuclear force between proton-proton force at nuclear distances. During WW II he developed the proximity fuse. Following the war, he made important contributions to experimental seismology, radio astronomy, and optical astronomy.«
