6792 Akiyamatakashi           Discovered 1991 Nov. 30 by M. Akiyama and T. Furuta at Susono
Named in honor of Takashi Akiyama (b. 1923), a leader in youth education for many years in Kanaya, Shizuoka. Long interested in science, he taught the young people of this small town to appreciate the wonders of animals, plants, and especially the cosmos. He introduced the first discoverer to astronomy and taught him a great deal.
