16953 Besicovitch           Discovered 1998 May 27 by P. G. Comba at Prescott.
Abram Samuilovitch Besicovitch (1891-1970) taught at various institutions in the Soviet Union and later at the University of Cambridge. He had an astounding geometric intuition and proved many counter-intuitive results, particularly with regard to sets of points of fractal dimension.
