Hans Meerwein (May 20, 1879 in Hamburg, Germany – October 24, 1965 in Marburg, Germany) was a German chemist.
Several reactions and reagents bear his name, most notably the Meerwein–Ponndorf–Verley reduction, the Wagner–Meerwein rearrangement, the Meerwein arylation reaction, and Meerwein's salt.
Artur Mahraun (30 December 1890 – 29 March 1950) was the founder and leader of the Young German Order (Jungdeutscher Orden or Jungdo) and an early contender for the leadership of the right-wing youth in Weimar Germany.Born the son of a privy councillor in Kassel, Mahraun became a career soldier with the Prussian Army when he enlisted in the Prussian Infantry Regiment No. 83 in 1908. He served with distinction on the Eastern Front during First World War.Like many of his contemporaries he became involved in Freikorps activity after the Armistice, forming his own group, the Offizierkompagnie Kassel in January 1919. The group was restructured in May 1920 when the Jungdo was adopted and by 1921 Mahraun could call on 70,000 followers. A strong believer in law and order, he rejected revolutionary activity and instead called for Germany to reconcile with France and rebuild her prestige through Franco-German co-operation. At its peak Mahraun's movement, which sought a return to the Wandervogel spirit, could call on as many as 300,000 followers. After meeting Adolf Hitler during the Beer Hall Putsch he quickly became a critic of the Nazi leader.Mahraun entered the political arena in 1928 when he formed the People's National Reich Association (Völksnationale Reichsvereiningung) as an electoral arm of his movement, merging it with the German Democratic Party to form the German State Party in 1930. However the move was not a success as the new party performed very poorly at election. Mahraun's party and Jungdo were banned in 1933 and he was for a time imprisoned by the Gestapo.He was briefly associated with a group called the Nachbarschafts-Bewegung after the war until his death in Gütersloh in 1950.
Friedrich Wilhelm Eckhardt (25 February 1892 – 9 April 1961) was a German engineer and head of the design office for the Berliner Maschinenbau Aktien Gesellschaft vormals L. Schwartzkopff.
Helmut Hasse (German: [ˈhasə]; 25 August 1898 – 26 December 1979) was a German mathematician working in algebraic number theory, known for fundamental contributions to class field theory, the application of p-adic numbers to local class field theory and diophantine geometry (Hasse principle), and to local zeta functions.
Karl August Reinhardt (27 January 1895 – 27 April 1941) was a German mathematician whose research concerned geometry, including polygons and tessellations. He solved one of the parts of Hilbert's eighteenth problem, and is the namesake of the Reinhardt polygons.
Wilhelm Lenz (February 8, 1888 in Frankfurt am Main – April 30, 1957 in Hamburg) was a German physicist, most notable for his invention of the Ising model and for his application of the Laplace–Runge–Lenz vector to the old quantum mechanical treatment of hydrogen-like atoms.
Arthur Scherbius (30 October 1878 – 13 May 1929) was a German electrical engineer who invented the mechanical cipher Enigma machine. He patented the invention and later sold the machine under the brand name Enigma.
Scherbius offered unequalled opportunities and showed the importance of cryptography to both military and civil intelligence.
Gerhard Hessenberg (German: [ˈgɛʁ.hart ˈhɛsənˌbɛrk]; 16 August 1874 – 16 November 1925) was a German mathematician who worked in projective geometry, differential geometry, and set theory.
