15620 Beltrami           Discovered 2000 Apr. 29 by P. G. Comba at Prescott.
Eugenio Beltrami (1835-1900) was an Italian mathematician who held professorships at Pisa, Pavia and Rome. He contributed to the differential geometry of curves and surfaces, particularly the pseudosphere of constant negative curvature as a model of Lobachevskian geometry.
