19235 van Schurman           Discovered 1993 Nov. 9 by E. W. Elst at Caussols.
Anna Maria van Schurman (1607-1678) was the first female student at the University of Utrecht, although she was obliged to follow the courses from behind a curtain. Excelling in many disciplines, she was one of the most intellectual women in Europe. A true polyglot, she corresponded actively with scholars around the world.
