Konstantin Eduardovich Tsiolkovsky (Konstanty Ciołkowski, Константин Эдуардович Циолковский; September 17 (old style: September 5) 1857 - September 19 1935) was a Russian and Soviet rocket scientist who pioneered astronautic theory. Along with the Frenchman Robert Esnault-Pelterie, the Transylvanian German Hermann Oberth and the American Robert H. Goddard, he is one of the founding fathers of modern rocketry and astronautics. His works later inspired leading Soviet rocket-engineers Sergei Korolev and Valentin Glushko who contributed to the success of the Soviet space program.
