Engineered Stability
How long have composites been around? Where does the classical laminate theory come from? Who made the first modern fiber composite? This work in the history of materials science is the first examination of the strategies employed in the nineteenth and twentieth centuries in researching and developing hybrid materials. The author analyzes numerous sources which record a regular back and forth between applied design and exploratory materials engineering in building such “modular materials”. The motivations, ideas, and concepts of engineers, scientists, and other players in industry and research are also examined within the context of their day. This book presents the development and impor...
The Fate of Nazi Germany’s Jet Engineers
In April 1945, American forces were sweeping eastwards toward Berlin, in part advancing across territory that would eventually become part of the Soviet Occupation Zone. As they advanced, US troops uncovered major parts of the manufacturing facilities and the people associated with the engines that powered Germany’s last generation of military aircraft: the jet fighters and bombers. Understandably, the engine technology involved in powering these aircraft, such as the Messerschmitt Me 262 and the Arado Ar 234, was of great interest to the Allied nations. Among the many questions that needed to be answered was whether the Germans had made important breakthroughs in their successful use of t...
Red Prometheus
This analysis of the relationship between science and totalitarian rule in one of the most technically advanced countries in the East bloc examines professional autonomy under dictatorship and the place of technology in Communist ideology. In Cold War-era East Germany, the German tradition of science-based technology merged with a socialist system that made technological progress central to its ideology. Technology became an important part of East German socialist identity--crucial to how Communists saw their system and how citizens saw their state. In Red Prometheus, Dolores Augustine examines the relationship between a dictatorial system and the scientific and engineering communities in Ea...
Versagtes Vertrauen
Sie wurden erst gebraucht, dann geduldet und schließlich kaltgestellt. Vertrauen schenkte die SED ihnen nie; die Stasi bespitzelte sie und behinderte ihre Arbeit. Die Rede ist von bürgerlichen Wissenschaftlern, die – parteilos oder als SED-Mitglieder – in der Ulbricht-Ära bedeutsame Leistungen trotz widriger Umstände erbrachten und unter Honecker mithilfe der Stasi rasch aus ihren Funktionen verdrängt wurden. Die Studie zeigt die beeindruckende Aufbauleistung in den Disziplinen, die die wissenschaftlich-technische Revolution der 2. Hälfte des 20. Jahrhunderts prägten: die Mikroelektronik, die Raumforschung und die Kerntechnik. Sie wird ergänzt um neue Erkenntnisse zum Scheitern des Flugzeugbauprogramms der DDR.
Jet Web
The present book describes the development history of turbojet engines, mainly in the web-type triangle Great Britain (USA) - Germany - Switzerland from early beginnings in the 1920s up to the first practical usage in the 1950s, before the still unbroken, grand impact of aero propulsion technology on global air traffic started. interconnections are highlighted, including the considerable impact of axial-flow compressor design know-how of the Swiss/German company BBC Brown Boveri & Cie. on both sides. The author reveals significant undercurrents which led to a considerable exchange, and thus change in understanding of the technical-historical perspective, especially in the decisive years before WWII, and thus closes gaps in the unilateral views of this ground-breaking technical advancement. The old ‘Whittle vs. von Ohain Saga’ is not repeated in full, but addressed in sufficient detail to understand the considerably enlarged narrative scope.
Die getarnte Armee

Erdöl, Mais und Devisen
"Wenn Sie Ihre Wirtschaft auf Vordermann gebracht haben, dann kann man die Mauer wieder aufmachen", erklärte Nikita S. Chruschtschow gegenüber Walter Ulbricht am 26. Februar 1962. Der Mauerbau war letztlich auch eine Absage an den bis dahin offen ausgetragenen Wettstreit zwischen Ost und West über das bessere Wirtschaftssystem. Der Magnettheorie Kurt Schumachers und Konrad Adenauers hatte Otto Grotewohl eine ostdeutsche Variante entgegengesetzt, die von der Überlegenheit der Planwirtschaft in der DDR gegenüber der sozialen Marktwirtschaft in der Bundesrepublik ausging. Doch das auf dem V. Parteitag der SED proklamierte Ziel, die Bundesrepublik konsumpolitisch einzuholen, scheiterte – obwohl sich die Sowjetunion unter Chruschtschow sehr darum bemüht hatte, die DDR zum "Schaufenster" des Sozialismus herauszuputzen. Die wechselvolle und spannungsreiche Geschichte der ostdeutsch-sowjetischen Wirtschaftsbeziehungen in den 1950er und 1960er Jahren wird hier erstmals durch zentrale Dokumente aus Moskauer Archiven anschaulich gemacht.
