30418 Jakobsteiner           Discovered 2000 June 1 by P. G. Comba at Prescott.
Jakob Steiner (1796-1863) was a self-made Swiss farmer's son who later became a professor at the University of Berlin. He developed new methods in projective geometry that enabled him to prove many beautiful and often intricate theorems.
