Bonn is in the southernmost part of the Rhine-Ruhr region, Germany's largest metropolitan area, with over 11 million inhabitants.  - Karl Marx (5 May 1818  14 March 1883) was a German-born scientist, philosopher, economist, sociologist, journalist, and revolutionary socialist. Born in Trier to a middle-class family, he later studied political economy and Hegelian philosophy. As an adult, Marx became stateless and spent much of his life in London, England, where he continued to develop his thought in collaboration with German thinker Friedrich Engels and published various works, the most well-known being the 1848 pamphlet "The Communist Manifesto". His work has since influenced subsequent intellectual, economic, and political history.  - Konrad Hermann Joseph Adenauer (5 January 1876  19 April 1967) was a German statesman who served as the first post-war Chancellor of Germany (West Germany) from 1949 to 1963. He led his country from the ruins of World War II to a productive and prosperous nation that forged close relations with France, the United Kingdom and the United States. During his years in power West Germany achieved democracy, stability, international respect and economic prosperity (""Wirtschaftswunder"", German for "economic miracle"). He was the first leader of the Christian Democratic Union (CDU), a Christian Democratic party that under his leadership became, and has since usually been the most influential party in the country.  - The University of Bonn is a public research university located in Bonn, Germany. Founded in its present form in 1818, as the linear successor of earlier academic institutions, the University of Bonn is today one of the leading universities in Germany. The University of Bonn offers a large number of undergraduate and graduate programs in a range of subjects. Its library holds more than five million volumes. The University of Bonn has 544 professors and 32,500 students. Among its notable alumni and faculty are seven Nobel Laureates, three Fields Medalist, twelve Gottfried Wilhelm Leibniz Prize winners, Prince Albert, Pope Benedict XVI, Frederick III, Karl Marx, Heinrich Heine, Friedrich Nietzsche, Konrad Adenauer, and Joseph Schumpeter.

The league table was originally compiled and issued by Shanghai Jiaotong University in 2003, the first global ranking with multifarious indicators, after which a board of international advisories was established to provide suggestions. The publication currently includes world's overall and subject league tables, alongside independent regional "Greater China Ranking" and "Macedonian HEIs Ranking". ARWU is regarded as one of the three most influential and widely observed university measures, alongside "QS World University Rankings" and "Times Higher Education World University Rankings".  It is praised for its objective methodology but draws some condemnation for narrowly focusing on raw research power, undermining humanities and quality of instruction.  - Friedrich Wilhelm Nietzsche (15 October 1844  25 August 1900) was a German philosopher, cultural critic, poet, philologist, and Latin and Greek scholar whose work has exerted a profound influence on Western philosophy and modern intellectual history. He began his career as a classical philologist before turning to philosophy. He became the youngest ever to hold the Chair of Classical Philology at the University of Basel in 1869, at the age of 24. Nietzsche resigned in 1879 due to health problems that plagued him most of his life, and he completed much of his core writing in the following decade. In 1889, at age 44, he suffered a collapse and a complete loss of his mental faculties. He lived his remaining years in the care of his mother (until her death in 1897), and then with his sister Elisabeth Förster-Nietzsche, and died in 1900.  - Times Higher Education World University Rankings is an annual publication of university rankings by "Times Higher Education (THE)" magazine. The publisher had collaborated with Quacquarelli Symonds (QS) to publish the joint "THEQS World University Rankings" from 2004 to 2009 before it turned to Thomson Reuters for a new ranking system. The publication now comprises the world's overall, subject, and reputation rankings, alongside three regional league tables, "Asia", "Latin America", and "BRICS & Emerging Economies" which are generated by consistent methodology. It is considered as one of the most widely observed university measures together with "Academic Ranking of World Universities" and "QS World University Rankings". It is praised for having a new improved methodology but undermining non-English-instructing institutions and being commercialized are the major criticisms.  - Friedrich Christian Diez ( 15 March 1794 -- 29 May 1876 ) was a philologist . The two works on which his fame rests are the Grammar of the Romance Languages ( published 1836 - 1844 ) , and the Etymological Dictionary of the Romance Languages ( 1853 , and later editions ) . He spent most of his career at University of Bonn .  - Christian Johann Heinrich Heine (13 December 1797  17 February 1856) was a German poet, journalist, essayist, and literary critic. He is best known outside Germany for his early lyric poetry, which was set to music in the form of "Lieder" (art songs) by composers such as Robert Schumann and Franz Schubert. Heine's later verse and prose are distinguished by their satirical wit and irony. He is considered part of the Young Germany movement. His radical political views led to many of his works being banned by German authorities. Heine spent the last 25 years of his life as an expatriate in Paris.  - The Gottfried Wilhelm Leibniz Prize is a program of the Deutsche Forschungsgemeinschaft (the German Research Foundation) which awards prizes to exceptional scientists and academics for their outstanding achievements in the field of research. It was established in 1985 and up to ten prizes are awarded annually to individuals or research groups working at a research institution in Germany or at a German research institution abroad.
