26661 Kempelen           Discovered 2000 Nov. 27 by P. Kušnirák at Ondřejov.
Wolfgang Kempelen (1734-1804), a polymath, mechanic and inventor, constructed a speech machine in 1778 based on imitating the human vocal organs. His most famous inventions are a chess machine, a writing machine for the blind and a pressurised conduit that took water from the Danube to Bratislava Castle.
