6734 Benzenberg           Discovered 1992 Mar. 23 by S. Ueda and H. Kaneda at Kushiro.
German physicist and astronomer Johann Friedrich Benzenberg (1777-1846) organized a school for surveyors and made an early demonstration of the rotation of the earth. He wrote a Handbuch der angewandten Geometrie (1815) and established the Bilk Observatory at Düsseldorf.
