German inventor and early rocketry theorist who, in a widely reported 1891 lecture in Berlin, proposed using reaction propulsion to launch a crewed vehicle beyond Earth's atmosphere. His speculative designs predate the more rigorous mathematical treatments of Tsiolkovsky and Goddard and mark him as one of the earliest people to publicly argue that spaceflight was physically achievable.
