George R. Carruthers

Born 1 Oct 1939.Black-American astrophysicist who was the principal inventor of a new space camera to measure ultraviolet light which can be used to identify interstellar atoms and molecules. After several years in development, it was taken to the moon on the Apollo 16 mission (1972). Positioned on the moon's surface, the camera could also image the gases of the Earth's atmosphere. The concentration of the pollutants, such as carbon monoxide, in the air surrounding large cities could be determined for many cities at the same time. Other space cameras developed by Carruthers and his colleagues have surveyed the ozone layer and transmitted photos of distant stars and planets for computer analysis. He also pioneered in the development of electronic telescopes.
