It was in the area of general relativity that he gained more fame, however, as he found the first exact solution to Einstein's field equations for a stationary, isolated spherically-symmetric mass.
During his tenure as the director of the observatory at Gottingen, he introduced methods of precision photometry using photographic plates and the use of coarse gratings for determining stellar magnitude and color. It was in the area of general relativity that he gained more fame, however, as he found the first exact solution to Einstein's field equations for a stationary, isolated spherically-symmetric mass. This metric bears his name today and demonstrates that bodies of sufficiently large mass and small radius have an escape velocity exceeding the speed of light. FTP, name this scientist, the namesake of the radius which defines the event horizon for a black hole.
