Konstantin Sergeyevich Stanislavski was a seminal Soviet Russian theatre practitioner. He was widely recognized as an outstanding character actor, and the many productions that he directed garnered him a reputation as one of the leading theatre directors of his generation. His principal fame and influence, however, rests on his "system" of actor training, preparation, and rehearsal technique.
Konstantin Andreyevich Trenyov was a Soviet Russian writer and playwright, USSR State Prize laureate (1941), best known for his Russian Civil War history drama Lyubov Yarovaya (1926).
Konstantin Eduardovich Tsiolkovsky was a Russian and Soviet rocket scientist who pioneered astronautics. Along with Robert Esnault-Pelterie, Hermann Oberth, Fritz von Opel and 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.
Tsiolkovsky spent most of his life in a log house on the outskirts of Kaluga, about 200 km (120 mi) southwest of Moscow. A recluse by nature, his unusual habits made him seem bizarre to his fellow townsfolk.
