Karl Becker (general)
Karl Heinrich Emil Becker (14 September 1879 – 8 April 1940) was a German weapons engineer and artillery general. He advocated and implemented close ties of the military to science for purposes of advanced weapons development. He was the head of the Army Ordnance Office, Senator of the Kaiser Wilhelm Society, first president of the Reich Research Council, the first general officer to be a member of the Prussian Academy of Sciences, as well as being a professor at both the University of Berlin and Technische Universität Berlin. In the late 1920s, he realised that a loophole in the Treaty of Versailles allowed Germany to develop rocket weapons. The military-scientific infrastructure he helped implement supported the German nuclear energy program, known as the Uranium Club. Being depressed over heavy criticism from Hitler for shortfalls in munitions production, he committed suicide in 1940. He was given a State funeral. Career From 1898, Becker was a military engineer. From 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Waffenamt
(WaA) was the German Army Weapons Agency. It was the centre for research and development of the Weimar Republic and later the Third Reich for weapons, ammunition and army equipment to the German Reichswehr and then Wehrmacht. It was founded 8 November 1919 as (RWA), and 5 May 1922 the name was changed to (HWA). The task of overseeing Germany's gigantic pre-World War II German re-armament, rearmament program was given to the (the Army Acceptance Organization, commonly referred to as the ), a subsidiary of the . By 1940 the consisted of 25,000 personnel in five departments in 16 inspection areas, augmented by specially selected plant personnel who were assigned to assist the inspectors in each manufacturing facility. Later, in the middle of 1944, approximately 8,000 of these inspectors were "freed for service at the front". The was responsible for the testing and acceptance of all weapons, equipment and ammunition before delivery to the . Inspections were carried out acc ...

Big Bertha (howitzer)
The 42 centimeter 14 L/12 (short naval cannon), or ''Minenwerfer-Gerät'' (M-Gerät), popularly known by the name of Big Bertha, was a German Empire, German List of siege artillery, siege howitzer built by Krupp AG in Essen, Germany and fielded by the Imperial German Army from 1914 to 1918. The had a Caliber (artillery), calibre barrel, making it one of the List of the largest cannon by caliber, largest artillery pieces ever fielded. The designed in 1911 as an iteration of earlier super-heavy German siege guns intended to break modern fortresses in France and Belgium and entered production in 1912. Test firing began in early 1914 and the gun was estimated to be finished by October 1914. When the First World War broke out, the two guns, still prototypes, were sent to Liège, Belgium, and destroyed Forts Fort de Pontisse, Pontisse and Fort de Loncin, Loncin. German soldiers bestowed the gun with the nickname "Big Bertha", which then spread through German newspapers to the Alli ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Humboldt University Of Berlin
The Humboldt University of Berlin (, abbreviated HU Berlin) is a public research university in the central borough of Mitte in Berlin, Germany. The university was established by Frederick William III on the initiative of Wilhelm von Humboldt, Johann Gottlieb Fichte and Friedrich Daniel Ernst Schleiermacher as the University of Berlin () in 1809, and opened in 1810. From 1828 until its closure in 1945, it was named the (Royal) Friedrich Wilhelm University of Berlin (FWU Berlin; ). During the Cold War, the university found itself in East Berlin and was ''de facto'' split in two when the Free University of Berlin opened in West Berlin. The university received its current name in honour of Alexander and Wilhelm von Humboldt in 1949. The university is divided into nine faculties including its medical school shared with the Freie Universität Berlin. The university has a student enrollment of around 35,000 students, and offers degree programs in some 171 disciplines from un ...

Wernher Von Braun
Wernher Magnus Maximilian Freiherr von Braun ( ; ; 23 March 191216 June 1977) was a German–American aerospace engineer and space architect. He was a member of the Nazi Party and '' Allgemeine SS'', the leading figure in the development of rocket technology in Nazi Germany, and later a pioneer of rocket and space technology in the United States. As a young man, von Braun worked in Nazi Germany's rocket development program. He helped design and co-developed the V-2 rocket at Peenemünde during World War II. The V-2 became the first artificial object to travel into space on 20 June 1944. Following the war, he was secretly moved to the United States, along with about 1,600 other German scientists, engineers, and technicians, as part of Operation Paperclip. He worked for the United States Army on an intermediate-range ballistic missile program, and he developed the rockets that launched the United States' first space satellite Explorer 1 in 1958. He worked with Walt Disney ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V2 Rocket
The V2 (), with the technical name ''Aggregat-4'' (A4), was the world's first long-range guided ballistic missile. The missile, powered by a liquid-propellant rocket engine, was developed during the Second World War in Nazi Germany as a " vengeance weapon" and assigned to attack Allied cities as retaliation for the Allied bombings of German cities. The rocket also became the first artificial object to travel into space by crossing the Kármán line (edge of space) with the vertical launch of MW 18014 on 20 June 1944. Research of military use of long-range rockets began when the graduate studies of Wernher von Braun were noticed by the German Army. A series of prototypes culminated in the A4, which went to war as the . Beginning in September 1944, more than 3,000 were launched by the Wehrmacht against Allied targets, first London and later Antwerp and Liège. According to a 2011 BBC documentary, the attacks from resulted in the deaths of an estimated 9,000 civilians and mil ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Walter Dornberger
Major-General Dr. Walter Robert Dornberger (6 September 1895 – 26 June 1980) was a German Army artillery officer whose career spanned World War I and World War II. He was a leader of Nazi Germany's V-2 rocket programme and other projects at the Peenemünde Army Research Centre. After the war, the US Nazi scientist recruitment programme Operation Paperclip saw him move to the US, largely avoiding punishment for involvement in war crimes, to work for some decades in high positions in aerospace, including for Bell Aircraft and Boeing. Early life Dornberger was born in Gießen in 1895. In 1914 he enlisted in the German army during World War 1. In October 1918, as an artillery lieutenant, Dornberger was captured by United States Marines and spent two years in a French prisoner of war camp, mostly in solitary confinement because of repeated escape attempts. In the late 1920s, Dornberger completed an engineering course with distinction at the Berlin Technical Institute, an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
German Nuclear Energy Project
Nazi Germany undertook several research programs relating to nuclear technology, including nuclear weapons and nuclear reactors, before and during World War II. These were variously called () or (). The first effort started in April 1939, just months after the discovery of nuclear fission in Berlin in December 1938, but ended shortly ahead of the September 1939 German invasion of Poland, for which many German physicists were drafted into the . A second effort under the administrative purview of the 's began on September 1, 1939, the day of the invasion of Poland. The program eventually expanded into three main efforts: (nuclear reactor) development, uranium and heavy water production, and uranium isotope separation. Eventually, the German military determined that nuclear fission would not contribute significantly to the war, and in January 1942 the turned the program over to the Reich Research Council () while continuing to fund the activity. The program was split up among ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phenol
Phenol (also known as carbolic acid, phenolic acid, or benzenol) is an aromatic organic compound with the molecular formula . It is a white crystalline solid that is volatile and can catch fire. The molecule consists of a phenyl group () bonded to a hydroxy group (). Mildly acidic, it requires careful handling because it can cause chemical burns. It is acutely toxic and is considered a health hazard. Phenol was first extracted from coal tar, but today is produced on a large scale (about 7 million tonnes a year) from petroleum-derived feedstocks. It is an important industrial commodity as a precursor to many materials and useful compounds, and is a liquid when manufactured. It is primarily used to synthesize plastics and related materials. Phenol and its chemical derivatives are essential for production of polycarbonates, epoxies, explosives such as picric acid, Bakelite, nylon, detergents, herbicides such as phenoxy herbicides, and numerous pharmaceuti ...

Cathode
A cathode is the electrode from which a conventional current leaves a polarized electrical device such as a lead-acid battery. This definition can be recalled by using the mnemonic ''CCD'' for ''Cathode Current Departs''. Conventional current describes the direction in which positive charges move. Electrons, which are the carriers of current in most electrical systems, have a negative electrical charge, so the movement of electrons is ''opposite'' to that of the conventional current flow: this means that electrons flow ''into'' the device's cathode from the external circuit. For example, the end of a household battery marked with a + (plus) is the cathode. The electrode through which conventional current flows the other way, into the device, is termed an anode. Charge flow Conventional current flows from cathode to anode outside the cell or device (with electrons moving in the opposite direction), regardless of the cell or device type and operating mode. Cathode polarity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallurgy
Metallurgy is a domain of materials science and engineering that studies the physical and chemical behavior of metallic elements, their inter-metallic compounds, and their mixtures, which are known as alloys. Metallurgy encompasses both the science and the technology of metals, including the production of metals and the engineering of metal components used in products for both consumers and manufacturers. Metallurgy is distinct from the craft of metalworking. Metalworking relies on metallurgy in a similar manner to how medicine relies on medical science for technical advancement. A specialist practitioner of metallurgy is known as a metallurgist. The science of metallurgy is further subdivided into two broad categories: chemical metallurgy and physical metallurgy. Chemical metallurgy is chiefly concerned with the reduction and oxidation of metals, and the chemical performance of metals. Subjects of study in chemical metallurgy include mineral processing, the extraction ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
