Karl Mey (March 1879 – May 1945) was a prominent German industrial physicist who directed the research and development branch of Osram AG.
His presidency of the Deutsche Physikalische Gesellschaft, starting the year Hitler became Chancellor of Germany, was crucial in that organization's ability to assert its independence from National Socialist policies.
[1] After receipt of his doctorate, Mey was employed at the Militärversuchsamt Tegel and then at the Allgemeine Elektrizitäts-Gesellschaft, where he specialized in research and development of incandescent light bulbs.
After the merger of AEG, the Auer Company, and Siemens & Halske into Osram AG in Berlin, he supervised the whole research and development branch.
During the period 1933 to 1935, he was the president of the Deutsche Physikalische Gesellschaft (Acronym: DPG; translation: German Physical Society.).
