Herman Müntz
250px (Chaim) Herman Müntz (28 August 1884, in Łódź – 17 April 1956, in Sweden) was a German mathematician, now remembered for the Müntz approximation theorem. Biography He was born in Łódź (then in the Piotrków Governorate of the Russian Empire, now in Poland) in a secular Jewish family, who had adopted a German spelling of the surname ''Minc''. He was educated there and at the Friedrich-Wilhelms-Universität in Berlin, graduating in 1906. He wrote a doctoral dissertation there on partial differential equations and the Plateau problem, in 1910, supervised by H. A. Schwarz. In 1911 he moved to Munich. In the following years he published on projective geometry, iterative methods, and approximation theory. In 1914 he took a teaching position in a school near Heppenheim, and a year later another in Hochwaldhausen. He became a German citizen in 1919. At around that time he suffered a breakdown, and moved back to Poland with his wife. He shortly began publishing mat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaim Muntz

After completing his doctorate, Plessner worked in Marburg where he published a paper containing what is now called Plessner's theorem. It is a theorem concerning the boundary behaviour of functions meromorphic in the unit disk. Plessner submitted his habilitation, the extra post-doctoral qualification needed to lecture at a German university, to the faculty at the University of Giessen. ...

Arnold Walfisz
Arnold Walfisz (2 July 1892 – 29 May 1962) was a Jewish-Polish mathematician working in analytic number theory. Life After the ''Abitur'' in Warsaw (Poland), Arnold Walfisz studied (1909−14 and 1918−21) in Germany at Munich, Berlin, Heidelberg and Göttingen. Edmund Landau was his doctoral-thesis supervisor at the University of Göttingen. Walfisz lived in Wiesbaden from 1922 through 1927, then he returned to Warsaw, worked at an insurance company and at the mathematical institute of the university (habilitation in 1930). In 1935, together with , he founded the mathematical journal ''Acta Arithmetica''. In 1936, Walfisz became professor at the University of Tbilisi in the nation of Georgia (at the time a part of the Soviet Union). He wrote approximately 100 mathematical articles and three books.

Stephan Cohn-Vossen
Stefan Cohn-Vossen (28 May 1902 – 25 June 1936) was a mathematician, who was responsible for Cohn-Vossen's inequality and the Cohn-Vossen transformation is also named for him. He proved the first version of the splitting theorem. He was also known for his collaboration with David Hilbert on the 1932 book ''Anschauliche Geometrie'', translated into English as '' Geometry and the Imagination''. He was born in Breslau (then a city in the Kingdom of Prussia; now Wrocław in Poland). He wrote a 1924 doctoral dissertation at the University of Breslau (now the University of Wrocław) under the supervision of Adolf Kneser. He became a professor at the University of Cologne in 1930. He was barred from lecturing in 1933 under Nazi racial legislation, because he was Jewish.. In 1934 he emigrated to the USSR, with some help from Herman Müntz. While there, he taught at Leningrad University. He died in Moscow from pneumonia. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ernst Kolman
Ernst Kolman or Arnošt Yaromirovich Kolman (russian: Арношт Яромирович Кольман); 6 December 1892 – 22 January 1979) was a Marxist philosopher, who renounced his former activities as an ideological enforcer in Soviet science. At the age of 84 he sought asylum in Sweden and published a retraction of his previous activity. Biography He was born in Prague to a Jewish family and studied at Charles University.

International Congress Of Mathematicians
The International Congress of Mathematicians (ICM) is the largest conference for the topic of mathematics. It meets once every four years, hosted by the International Mathematical Union (IMU). The Fields Medals, the Nevanlinna Prize (to be renamed as the IMU Abacus Medal), the Carl Friedrich Gauss Prize, Gauss Prize, and the Chern Medal are awarded during the congress's opening ceremony. Each congress is memorialized by a printed set of Proceedings recording academic papers based on invited talks intended to be relevant to current topics of general interest. Being List of International Congresses of Mathematicians Plenary and Invited Speakers, invited to talk at the ICM has been called "the equivalent ... of an induction to a hall of fame".

Eberhard Hopf
Eberhard Frederich Ferdinand Hopf (April 4, 1902 in Salzburg, Austria-Hungary – July 24, 1983 in Bloomington, Indiana, USA) was a mathematician and astronomer, one of the founding fathers of ergodic theory and a pioneer of bifurcation theory who also made significant contributions to the subjects of partial differential equations and integral equations, fluid dynamics, and differential geometry. The Hopf maximum principle is an early result of his (1927) that is one of the most important techniques in the theory of elliptic partial differential equations.

The Enabling Act Of 1933
The Enabling Act (German: ') of 1933, officially titled ' (), was a law that gave the German Cabinet – most importantly, the Chancellor – the powers to make and enforce laws without the involvement of the Reichstag or Weimar President Paul von Hindenburg, leading to the rise of Nazi Germany. Critically, the Enabling Act allowed the Chancellor to bypass the system of checks and balances in the government. The act rested upon Article 48 of the Weimar Constitution which gave the government emergency powers during periods of unrest. Among these powers was the ability to create and enforce laws that could explicitly violate individual rights prescribed in the constitution. In January 1933, Adolf Hitler, leader of the Nazi Party, was appointed as chancellor, the head of the German government. On February 27, the German parliament building — the Reichstag — caught fire. Acting as chancellor, Hitler immediately accused the communists of being the perpetrators of the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
