Konstantin Eduardovich Tsiolkovsky (September 17 [O.S. September 5] 1857 – September 19, 1935) was an Imperial Russian and Soviet rocket scientist and pioneer of the astronautic theory. He is considered by many to be the father of theoretical 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 misanthrope by nature, he appeared strange and bizarre to his fellow-town folk.
