Life

Edmund Germer studied physics in Berlin and Rostock . Later he was chief physicist at Rectron GmbH, which was founded in 1925 . Germer is considered to be the father of the fluorescent lamp by proposing in 1926 to increase the pressure inside tubes and to coat the tubes with a fluorescent substance that converts ultraviolet radiation into visible light.

In 1926, together with the scientists Friedrich Meyer and Hans Spanner, he published a description of how ignition at low voltage values ​​can be facilitated by preheating the electrodes. On December 19, 1927, they filed the United States Patent 2182732 and on December 5, 1930 the United States Patent 2202199 for his discharge device . Both patents were later bought by General Electric .

In 1938 his son Helmut Germer was born. After the Second World War, he was invited by Engelhardt Industries in Newark, New Jersey to continue his research at Hanovia . In 1951 he also brought his wife and son to the USA. Between 1926 and 1952 he acquired 22 patents in the USA and 30 from Germany.
