Erich Hüttenhain
Erich Hüttenhain (26 January 1905 in Siegen – 1 December 1990 in Brühl) was a German academic mathematician and cryptographer (Cryptography) and considered a leading cryptanalyst in the Third Reich. He was Head of the cryptanalysis unit at OKW/Chi, the Cipher Department of the High Command of the Wehrmacht. Life and work Hüttenhain was the son of a Conrector and studied after the high school diploma (german: Abitur) 1924 in Siegen at the University of Marburg, the Johann Wolfgang Goethe-University Frankfurt and the University of Münster. He studied mathematics with Heinrich Behnke and astronomy at Münster. There he was assistant to Martin Lindow (1880–1967), who was director of the observatory at Münster. In 1933, at the University of Münster, he took his examination for promotion of Dr. phil. in astronomy under Lindow with the thesis titled: ''Spatial infinitesimal orbits around the libration points in the straight-line case of the (3 + 1) bodies''. In 1936, he ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Moreover, its historical stock encompasses one of the most important manuscript collections of the world, the largest collection of incunabula worldwide, as well as numerous further important special collections. Its collection of historical prints before 1850 number almost one million units. The legal deposit law has been in force since 1663, regulating that two copies of every printed work published in Bavaria have to be submitted to the Bayerische Staatsbibliothek. This law is still applicable today. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Burschenschaft
A Burschenschaft (; sometimes abbreviated in the German ''Burschenschaft'' jargon; plural: ) is one of the traditional (student associations) of Germany, Austria, and Chile (the latter due to German cultural influence). Burschenschaften were founded in the 19th century as associations of university students inspired by liberal and nationalistic ideas. They were significantly involved in the March Revolution and the unification of Germany. After the formation of the German Empire in 1871, they faced a crisis, as their main political objective had been realized. So-called were established, but these were dissolved by the Nazi regime in 1935/6. In West Germany, the were re-established in the 1950s, but they faced a renewed crisis in the 1960s and 1970s, as the mainstream political outlook of the German student movement of that period swerved to the radical left. Roughly 160 exist today in Germany, Austria and Chile. History Origins The very first one, called ("original "), ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Nazi Germany
Nazi Germany (lit. "National Socialist State"), ' (lit. "Nazi State") for short; also ' (lit. "National Socialist Germany") (officially known as the German Reich from 1933 until 1943, and the Greater German Reich from 1943 to 1945) was the German state between 1933 and 1945, when Adolf Hitler and the Nazi Party controlled the country, transforming it into a dictatorship. Under Hitler's rule, Germany quickly became a totalitarian state where nearly all aspects of life were controlled by the government. The Third Reich, meaning "Third Realm" or "Third Empire", alluded to the Nazi claim that Nazi Germany was the successor to the earlier Holy Roman Empire (800–1806) and German Empire (1871–1918). The Third Reich, which Hitler and the Nazis referred to as the Thousand-Year Reich, ended in May 1945 after just 12 years when the Allies defeated Germany, ending World War II in Europe. On 30 January 1933, Hitler was appointed chancellor of Germany, the head of gove ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Otto Leiberich
Otto Leiberich (5 December 1927 in Crailsheim - 23 June 2015) was a German cryptologist and mathematician. Leiberich is most notable for establishing the Bundesamt für Sicherheit in der Informationstechnik in 1991. Life Leiberich started his career during World War II, conscripted as a soldier and working as a cryptanalyst in Chi IV of the OKW/Chi. After studying mathematics and physics at the University of Cologne, Leiberich earned a Dr. phil. in 1953 at the same university with a topic on algebra; his thesis (german: "Über Systeme von Jardenschen Folgen", On systems of Jarden sequences) was supervised by Guido Hoheisel. Leiberich joined the newly established post war German cipher bureau that from 1956 on was called the ''Central Cryptography Office'' (german: Zentralstelle für das Chiffrierwesen (ZfCh)). Dr Erich Hüttenhain was his director, both in OKW/Chi and in the new bureau. Career During the Cold War Leiberich and his team worked intensively on the crypt ...

TICOM
TICOM (Target Intelligence Committee) was a secret Allied project formed in World War II to find and seize German intelligence assets, particularly in the field of cryptology and signals intelligence. It operated alongside other Western Allied efforts to extract German scientific and technological information and personnel during and after the war, including Operation Paperclip (for rocketry), Operation Alsos (for nuclear information) and Operation Surgeon (for avionics). Competition with the Soviet Union for these same spoils of war was intense, with direct payoffs including missile technology that led both to a heightened Cold War stalemate and landing a man on the Moon. History The project was initiated by the British, but when the US Army Chief of Staff General George Marshall learnt of it, it soon became Anglo-American. The aim was to seek out and capture the cryptologic secrets of Germany. The concept was for teams of cryptologic experts, mainly drawn from the code-breakin ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SIGABA
In the history of cryptography, the ECM Mark II was a cipher machine used by the United States for message encryption from World War II until the 1950s. The machine was also known as the SIGABA or Converter M-134 by the Army, or CSP-888/889 by the Navy, and a modified Navy version was termed the CSP-2900. Like many machines of the era it used an electromechanical system of rotors to encipher messages, but with a number of security improvements over previous designs. No successful cryptanalysis of the machine during its service lifetime is publicly known. History It was clear to US cryptographers well before World War II that the single-stepping mechanical motion of rotor machines (e.g. the Hebern machine) could be exploited by attackers. In the case of the famous Enigma machine, these attacks were supposed to be upset by moving the rotors to random locations at the start of each new message. This, however, proved not to be secure enough, and German Enigma messages were freque ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
