24907 Alfredhaar           Discovered 1997 Feb. 4 by P. G. Comba at Prescott.
Alfred Haar (1885-1933) was a Hungarian mathematician who worked on real and complex analysis and the calculus of variations. His fame rests mostly on the establishment of a measure on locally compact groups, now referred to as the Haar measure.
