A short popular handbook first issued in German in 1949 as Kleine Raketenkunde (Mundus-Verlag, Stuttgart) and translated into French in 1954 by René Rodier for Amiot-Dumont's Bibliothèque de l'Aviation, edited by General Corniglion-Molinier. Across five chapters and two appendices (annotated bibliography, technical glossary), Hans K. Kaiser surveys rocket history from antiquity to 1953, explains reaction-propulsion principles, sketches the foundational work of Goddard, Oberth and Sänger and of the Gesellschaft für Weltraumforschung, then details modern developments with a substantial section on German wartime missiles (A4/V-2) and early postwar American programmes. The book opens with a Hermann Oberth epigraph.
