Lloyd Berkner

Lloyd Berkner Much ( born 1 February 1905 in Milwaukee, Wisconsin, † June 4, 1967 in Washington, DC) was an American physicist and founder of the International Geophysical Year.

Berkner developed together with Wells Ionosonde a novel that is still used today as the standard unit for measuring the density and height of the ionosphere.

In 1959 he became director of the Green Bank Observatory and approved Frank Drake's Project Ozma, the world's first SETI program. After Berkner the Antarctic Berkner Island and the northwest of that location, submarine Berkner Bank are named, also a crater on the moon back.
