Robert König
Robert Johann Maria König (11 April 1885, Linz – 9 July 1979, Munich) was an Austrian mathematician. He studied from 1903 to 1907 at the University of Vienna and at the University of Göttingen, where he received his PhD under David Hilbert with thesis ''Oszillationseigenschaften der Eigenfunktionen der Integralgleichung mit definitem Kern und das Jacobische Kriterium der Variationsrechnung''.

Linz
Linz (Pronunciation: , ; ) is the capital of Upper Austria and List of cities and towns in Austria, third-largest city in Austria. Located on the river Danube, the city is in the far north of Austria, south of the border with the Czech Republic. As of 1 January 2024, the city has a population of 212,538. It is the seventh-largest of all List of cities and towns on the river Danube, cities on the river Danube. History Linz originated as a Roman Empire, Roman fort named ''Lentia'', established in the first century. The name reflects its location at a bend in the Danube (Celtic languages, Celtic root ''lentos'' = "bendable"). This strategic position on the river made it the first Roman fort in the Noricum region, protecting a vital transportation route. The name "Linz" in its present form was first documented in 799. Linz was mentioned as a fortified city in 1236 and was granted city rights in 1324. Johannes Kepler spent several years of his life in the city teaching m ...

Leon Lichtenstein
Leon Lichtenstein (16 May 1878 – 21 August 1933) was a Polish-German mathematician, who made contributions to the areas of differential equations, conformal mapping, and potential theory. He was also interested in theoretical physics, publishing research in hydrodynamics and astronomy. Life and work Leon Lichtenstein was born on 16 May 1878 to an Ashkenazi Jewish family in Warsaw, then part of the Russian Empire. His cousin, Leo Wiener, was the father of MIT mathematician Norbert Wiener.

University Of Vienna Alumni
A university () is an institution of tertiary education and research which awards academic degrees in several academic disciplines. ''University'' is derived from the Latin phrase , which roughly means "community of teachers and scholars". Universities typically offer both undergraduate and postgraduate programs. The first universities in Europe were established by Catholic monks. The University of Bologna (), Italy, which was founded in 1088, is the first university in the sense of: *being a high degree-awarding institute. *using the word (which was coined at its foundation). *having independence from the ecclesiastic schools and issuing secular as well as non-secular degrees (with teaching conducted by both clergy and non-clergy): grammar, rhetoric, logic, theology, canon law and notarial law.Hunt Janin: "The university in medieval life, 1179–1499", McFarland, 2008, , p. 55f.de Ridder-Symoens, Hilde''A History of the University in Europe: Volume 1, Universities in the Midd ...

Scientists From Linz
A scientist is a person who researches to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales ( 624–545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Bayerische Akademie Der Wissenschaften
The Bavarian Academy of Sciences and Humanities () is an independent public institution, located in Munich. It appoints scholars whose research has contributed considerably to the increase of knowledge within their subject. The general goal of the academy is the promotion of interdisciplinary encounters and contacts and the cooperation of representatives of different subjects. History On 12 October 1758 the lawyer Johann Georg von Lori (1723–1787), Privy Counsellor at the College of Coinage and Mining in Munich, founded the ''Bayerische Gelehrte Gesellschaft'' (Learned Society of Bavaria). This led to the foundation by Maximilian III Joseph, Elector of Bavaria, of the Bavarian Academy of Sciences and Humanities on 28 March 1759. Count Sigmund von Haimhausen was the first president. The Academy's foundation charter specifically mentions the Parnassus Boicus, an earlier learned society. Originally, the Academy consisted of two divisions, the Class for History (''Historische ...
