A self-taught, largely deaf schoolteacher in provincial Russia who worked out the mathematics of rocket-powered spaceflight in near-total isolation. His 1903 paper derived what is now called the Tsiolkovsky rocket equation, relating a rocket's change in velocity to its exhaust velocity and mass ratio, and he proposed liquid propellants, multi-stage rockets and orbiting space stations before any of them existed. He never built a rocket himself, but his theoretical work underpins the entire field and directly influenced Soviet rocketry, including Korolev.
