6266 Letzel           Discovered 1986 Oct. 4 by A. Mrkos at Klet.
Named in memory of Jan Letzel (1880-1925), Czech architect inspired by the Art Nouveau style and who worked in Japan from 1907 to 1923. He designed the Hiroshima Prefectural Commercial Exhibition Hall in 1915. This building, the most elegant in the city, became world famous as the Genbaku Dome or A-bomb Dome, which was left in ruins as an eternal symbol of the tragedy of Hiroshima on 1945 Aug. 6. Name suggested by J. Ticha.
