Konstantin Eduardovich Tsiolkovsky (17 September [O.S. 5 September] 1857 – 19 September 1935) was an Imperial Russian and Soviet rocket scientist and pioneer of the astronautic theory. Along with the German Hermann Oberth and the American Robert H. Goddard, he is considered to be one of the founding fathers of rocketry and astronautics. His works later inspired leading Soviet rocket engineers such as Sergey Korolyov and Valentin Glushko and contributed to the early success of the Soviet space program.
Tsiolkovsky spent most of his life in a log house on the outskirts of Kaluga, about 200 km (125 miles) southwest of Moscow. A recluse by nature, he appeared strange and bizarre to his fellow town-folk.
