DIE RAKETE ZUR HOHENFORSCHUNG: EIN BEITRAG ZUM RAUMFAHRTPROBLEM. Leipzig und Berlin: Verlag Hachmeister & Thal, 1934. Octavo, pp. [1-2] 3-16, nine diagrams in the text, original printed yellow wrappers. First edition. Vladimír Mandl (1899-1941) was a Czechoslovak jurist and professor who published works on aviation law and the first monograph on space law. "Mandl not only studied intensively the literature on the possibility of traveling in space, he also closely followed the experiments in rocketry. In 1932 he published a popular scientific work in Czech on the problem of interstellar transport. In it he provided an overview of the work of Konstantin Ziolkowski, Hermann Oberth, Robert Goddard and other rocket researchers. The book also contained a blueprint for a multi-stage rocket designed by Mandl himself for altitude research, which had a mixed drive with solid and liquid fuel and which should be designed for an altitude of up to 250 kilometers. Mandl filed for a patent on the rocket on April 14, 1932 in the Czech Republic, and on September 25, 1933, it was patented under patent number 52236 of class 46d. Mandl also published the design of his rocket in Germany. In Leipzig a brief description appeared in 1934 under the title DIE RAKETE ZUR HOHENFORSCHUNG: EIN BEITRAG ZUM RAUMFAHRTPROBLEM [The Rocket for Altitude Research: A Contribution to the Space Problem]." - Wikipedia.
