74764 Rudolfpešek | Discovered 1999 Sept. 15 by P. Kušnirák and P. Pravec at Ondřejov. |
Rudolf Pešek (1905-1989) founded the Czech school of aerodynamic engineering. An enthusiastic supporter and popularizer of spaceflight, he became an active member of the International Astronautical Federation and the International Academy of Astronautics. He invented the famous abbreviation CETI, now SETI. |
