Gerhard Wilhelm Goetze (June 19, 1930 – January 17, 2007) was a German-born Ph.D. researcher and inventor in atomic physics. He was primarily known for his work on the Moon-to-Earth Apollo TV camera making live broadcast in both brilliant sunlight and pitch darkness possible. Goetze discovered the secondary electron conduction (SEC) effect which amplified light through high-speed electrons deposited in thin film storage targets. The SEC tube was additionally used in ground-based astronomy, inspection of integrated circuits, electron-microscope-based biological tissue study, security, and night vision. Goetze received ten patents for his inventions.
