Eugen Sänger (1905-1964) was one of Germany's leading rocket pioneers, starting as a member of the nation's amateur rocketry movement during the 1920s and studying aeronautics at university. His first thesis attempt, on rocket-powered flight, was rejected for being too fanciful, but in 1933 he published it as the book Raketenflugtechnik. This was 'the first study leading to the eventual development of a reusable human-piloted rocket-powered space plane, a concept which evolved into the X-planes and the space shuttle' (Norman, History of Information). During the Second World War he worked for the Reich Air Ministry, and unsuccessfully attempted to convert the concept into a rocket-powered, long-range bomber. He also made significant contributions to engine technology, introducing the force-cooled ramjet design that is now standard. After the war Sänger worked for the French government before founding a research centre in Stuttgart.

ABOUT: Space Flight: Countdown for the Future (1965) Eugen Sänger's 1965 book presents a sweeping, historically informed survey of humanity's pursuit of space travel, blending the origins of astronautics with forward?looking speculation on how spaceflight might evolve. It reflects Sänger's stature as a pioneering aerospace engineer and offers both a retrospective of early rocketry and a projection of future possibilities. 1. The History of Spaceflight Dreams Sänger traces the lineage of spaceflight concepts from early imaginative visions to the scientific foundations laid by pioneers such as Hermann Oberth (whose work originally inspired Sänger's own career). The book situates mid?20th?century space achievements within this longer intellectual arc. 2. Engineering Principles and Rocket Development Drawing on his background in lifting?body research and ramjet innovation, Sänger outlines the physics and engineering challenges of escaping Earth's gravity, achieving orbital velocity, and designing vehicles capable of sustained space travel. 3. The State of Space Technology in the Mid?1960s Published at the height of the Space Race, the book captures the technological optimism of the era. Sänger discusses the capabilities of contemporary rockets, spacecraft, and propulsion systems, offering a snapshot of the field just before the Apollo landings. 4. Speculation on the Future of Space Exploration True to its subtitle, the book looks ahead?imagining how humanity might expand into space through improved propulsion, reusable vehicles, and long?range missions. Sänger's projections reflect both engineering realism and visionary ambition.
