Died 19 Sep 1935 at age 78 (born 17 Sep 1857). Russian pioneer space theorist who, while a provincial Russian schoolteacher, worked out many of the principles of space travel.

He wrote various papers, including the 1903 article “Exploration of Space with Reactive Devices.” The engineering equations he derived included parameters such as specific impulse, thrust coefficient and area ratio.
