Martin Schwarzschild (1912-1997), German-American astronomer. Schwarzchild's work was on stellar structure and stellar evolution. He designed Stratoscope I, the first of two stratoscopes. These were balloon-borne optical and infrared telescopes that were used to study astronomical phenomena. Schwarzschild used Stratoscope I to study turbulence and granulation in the Sun's photosphere. Schwarzchild was also the son of the German astronomer Karl Schwarzchild (1873-1916), who identified the critical point at which stars become black holes.
