Konstantin Eduardovich Tsiolkovsky was born Sept. 17, 1857, in Izhevskoye , Russia. He was the son of a Polish deportee to Siberia. At ten he nearly became deaf from scarlet fever and had to quit school. He refused to be handicapped by his deafness and continued his education on his own at home. He read Jules Verne's stories of space travel and began to write science fiction stories himself. He introduced elements of science and technology into his stories, such as the problem of controlling a rocket as it moved between gravitational fields.

In 1894 Tsiolkovsky designed a monoplane that was not flown until 1915. He built the first Russian wind tunnel in 1897. He also thought about the uses of his beloved rockets to explore and master space. He was the author of Investigations of Outer Space by Rocket Devices (1911) and Aims of Astronauts (1914). It was Tsiolkovsky who used mathematics and physics to study and model the manner in which they operated, called rocket dynamics. In 1903 he published the rocket equation in a Russian aviation magazine. Called the Tsiolkovsky formula, it established the relationships among rocket speed, the speed of the gas at exit, and the mass of the rocket and its propellant. This equation is the basis of much of the spacecraft engineering done today. In 1929 he published his theory of multistage rockets, based on his knowledge of propulsion dynamics.
