In 1926 he completed his doctorate under Carl Ramsauer at the Danzig Technische Hochschule. He completed his Habilitation in 1927.Hentschel, 1966, Appendix F; see the entry for Brüche. Career Until 1933, Brüche was an unpaid lecturer on experimental and technical physics at the Danzig Technische Hochschule, where he worked on the measurement of electron scattering cross-sections of molecular gases. From 1928 to 1945, he was head of the physics laboratories at the Allgemeine Elektrizitäts-Gesellschaft (AEG) in Reinickendorf, a borough of Berlin. At the AEG, he worked mostly on ge ...

Mannheim
Mannheim (; Palatine German: or ), officially the University City of Mannheim (german: Universitätsstadt Mannheim), is the second-largest city in the German state of Baden-Württemberg after the state capital of Stuttgart, and Germany's 21st-largest city, with a 2020 population of 309,119 inhabitants. The city is the cultural and economic centre of the Rhine-Neckar Metropolitan Region, Germany's seventh-largest metropolitan region with nearly 2.4 million inhabitants and over 900,000 employees. Mannheim is located at the confluence of the Rhine and the Neckar in the Kurpfalz (Electoral Palatinate) region of northwestern Baden-Württemberg. The city lies in the Upper Rhine Plain, Germany's warmest region. Together with Hamburg, Mannheim is the only city bordering two other federal states.

Electron Microscope
An electron microscope is a microscope that uses a beam of accelerated electrons as a source of illumination. As the wavelength of an electron can be up to 100,000 times shorter than that of visible light photons, electron microscopes have a higher resolving power than light microscopes and can reveal the structure of smaller objects. A scanning transmission electron microscope has achieved better than 50 pm resolution in annular dark-field imaging mode and magnifications of up to about 10,000,000× whereas most light microscopes are limited by diffraction to about 200 nm resolution and useful magnifications below 2000×. Electron microscopes use shaped magnetic fields to form electron optical lens systems that are analogous to the glass lenses of an optical light microscope. Electron microscopes are used to investigate the ultrastructure of a wide range of biological and inorganic specimens including microorganisms, cells, large molecules, biopsy samples, ...

Berlin
Berlin ( , ) is the capital and largest city of Germany by both area and population. Its 3.7 million inhabitants make it the European Union's most populous city, according to population within city limits. One of Germany's sixteen constituent states, Berlin is surrounded by the State of Brandenburg and contiguous with Potsdam, Brandenburg's capital. Berlin's urban area, which has a population of around 4.5 million, is the second most populous urban area in Germany after the Ruhr. The Berlin-Brandenburg capital region has around 6.2 million inhabitants and is Germany's third-largest metropolitan region after the Rhine-Ruhr and Rhine-Main regions. Berlin straddles the banks of the Spree, which flows into the Havel (a tributary of the Elbe) in the western borough of Spandau. Among the city's main topographical features are the many lakes in the western and southeastern boroughs formed by the Spree, Havel and Dahme, the largest of which is Lake Müggelsee. Due to its l ...

Habilitation
Habilitation is the highest university degree, or the procedure by which it is achieved, in many European countries. The candidate fulfills a university's set criteria of excellence in research, teaching and further education, usually including a dissertation. The degree, abbreviated "Dr. habil." (Doctor habilitatus) or "PD" (for "Privatdozent"), is a qualification for professorship in those countries. The conferral is usually accompanied by a lecture to a colloquium as well as a public inaugural lecture. History and etymology The term ''habilitation'' is derived from the Medieval Latin , meaning "to make suitable, to fit", from Classical Latin "fit, proper, skillful". The degree developed in Germany in the seventeenth century (). Initially, habilitation was synonymous with "doctoral qualification". The term became synonymous with "post-doctoral qualification" in Germany in the 19th century "when holding a doctorate seemed no longer sufficient to guarantee a proficient transfer o ...

Mosbach
Mosbach (; South Franconian: ''Mossbach'') is a town in the north of Baden-Württemberg, Germany. It is the seat of the Neckar-Odenwald district and has a population of approximately 25,000 distributed in six boroughs: Mosbach Town, Lohrbach, Neckarelz, Diedesheim, Sattelbach and Reichenbuch. Geography Located about 35 km east of Heidelberg, it is situated south of the Odenwald mountains at a height of 134-354m at the confluence of the Neckar and the Elz. The town is part of the conservation area Naturpark Neckartal-Odenwald and the UNESCO ''Geopark Bergstraße-Odenwald''. History The settlement of Mosbach developed around the Benedictine monastery of Mosbach Abbey (''"Monasterium Mosabach"''), the first written record of which dates from the 9th century. In 1241 rights and privileges had been granted to Mosbach as an Imperial free city. These rights were lost in 1362 when Mosbach became part of the Electorate of the Palatinate.

Carl Ramsauer
Carl Wilhelm Ramsauer (6 February 1879 – 24 December 1955) was a German professor of physics and research physicist, famous for the discovery of the Ramsauer–Townsend effect. He pioneered the field of electron and proton collisions with gas molecules.Mehra, Volume 1, Part 2, 2001, p. 620. Early life Ramsauer was born in Osternburg, Oldenburg. From 1897 to 1907, he studied at the Munich, Tübingen, Berlin, Kiel, London, and Breslau Universities. He was awarded his doctorate at Kiel.Hentschel, 1966, Appendix F, pp. XLII-XLII. Career From 1907 to 1909, Ramsauer was a teaching assistant to Philipp Lenard in the physics department at the Ruprecht Karl University of Heidelberg. It was here that he conducted research on the quantum effect of the transparency of noble gases to slow electrons, known as the Ramsauer–Townsend effect. Subsequently, he was a staff scientist at the Radiological Institute in Heidelberg. During World War I, he served as an artillery officer. Fr ...
