World War II-dated collection of Hans Hosenthien's handwritten notes, totaling eight pages on five sheets, deriving from Germany's Peenemunde Army Research Center where Hosenthien worked with the rocket development testing team. The pages were recovered as part of the cache of engineering papers taken during Operation Paperclip, when German rocket scientists including Wernher von Braun were taken into US custody. These pages of Hosenthien's notes contain multiple diagrams, charts, and mathematical expressions. Includes a printed Telefunken sheet. In overall fine condition, with trimming, folds, and area of paper loss to one sheet. The massive collection of German rocketry material taken by the US amounted to nearly fourteen tons and included drawings, test reports, technical schematics, and rocketry-related engineering and scientific studies. These papers represented a decade of intensive research and became the blueprint and primary foundation of America's entry into the missile and rocket development programs that would put Americans in space. As an original member of von Braun's team, Hosenthein proved invaluable as an engineer and worked his entire life with the rocket team at Fort Bliss, White Stands, and Huntsville, eventually being promoted to Head of Flight Dynamics Branch, Guidance and Control Division, NASA Marshall Space Flight Center. A fascinating collection of early papers from this early rocket pioneer. From the collection of aerospace memorabilia specialist Ken Havekotte.
