Wilhelm von Humboldt in the context of "Austronesian languages"

The Humboldt University of Berlin (German: Humboldt-Universität zu Berlin, abbreviated HU Berlin) is a public research university in the central borough of Mitte in Berlin, Germany.

The university was established by Frederick William III on the initiative of Wilhelm von Humboldt, Johann Gottlieb Fichte and Friedrich Daniel Ernst Schleiermacher as the University of Berlin (Universität zu Berlin) in 1809, and opened in 1810. From 1828 until its closure in 1945, it was named the (Royal) Friedrich Wilhelm University of Berlin (FWU Berlin; German: Königliche Friedrich-Wilhelms-Universität zu Berlin). During the Cold War, the university found itself in East Berlin and was de facto split in two when the Free University of Berlin opened in West Berlin. The university received its current name in honour of Alexander and Wilhelm von Humboldt in 1949.

Benjamin Atwood Lee Whorf (/hwɔːrf/; April 24, 1897 – July 26, 1941) was an American linguist and fire prevention engineer best known for proposing the Sapir–Whorf hypothesis. He believed that the structures of different languages shape how their speakers perceive and conceptualize the world. Whorf saw this idea, named after him and his mentor Edward Sapir, as having implications similar to those of Einstein's principle of physical relativity. However, the concept originated from 19th-century philosophy and thinkers like Wilhelm von Humboldt and Wilhelm Wundt.

Whorf initially pursued chemical engineering but developed an interest in linguistics, particularly Biblical Hebrew and indigenous Mesoamerican languages. His groundbreaking work on the Nahuatl language earned him recognition, and he received a grant to study it further in Mexico. He presented influential papers on Nahuatl upon his return. Whorf later studied linguistics with Edward Sapir at Yale University while working as a fire prevention engineer.

A research university or a research-intensive university is a university that is committed to research as a central part of its mission. They are "the key sites of knowledge production", along with "intergenerational knowledge transfer and the certification of new knowledge" through the awarding of doctoral degrees, and continue to be "the very center of scientific productivity". They can be public or private, and often have well-known brand names.

Undergraduate courses at many research universities are often academic rather than vocational and may not prepare students for particular careers, but many employers value degrees from research universities because they teach fundamental life skills such as critical thinking. Globally, research universities are overwhelmingly public institutions, while some countries like the United States and Japan also have well-known private research institutions.

Bildungsbürgertum (German: [ˈbɪldʊŋsˌbʏʁɡɐtuːm], "cultured / educated middle class") was a social class that emerged in mid-18th-century Germany as the educated social stratum of the bourgeoisie. It was a cultural elite that had received an education based on the values of idealism and classical studies and which steered public opinion in art and patterns of behaviour. The majority of its members were Protestant and employed in the upper civil service and free professions such as law, journalism and the arts. Despite its influence, the Bildungsbürgertum never exceeded more than about one percent of the population.

Wilhelm von Humboldt shaped the Bildungsbürgertum's ideal of education as a process of life-long learning that valued all-around knowledge over training for a profession. During the course of the nineteenth century, that ideal was slowly diluted as industrialisation and urbanisation increased the need for specialised scientific knowledge. "Secular religions" such as nationalism, social Darwinism, antisemitism and ideological imperialism became more prominent, and the class came to see its status more and more as an entitlement rather than an achievement.

Friedrich Wilhelm Heinrich Alexander von Humboldt (14 September 1769 – 6 May 1859) was a German polymath, geographer, naturalist, explorer, and proponent of Romantic philosophy and science. He was the younger brother of the Prussian minister, philosopher, and linguist Wilhelm von Humboldt (1767–1835). Humboldt's quantitative work on botanical geography laid the foundation for the field of biogeography, while his advocacy of long-term systematic geophysical measurement pioneered modern geomagnetic and meteorological monitoring. Humboldt and Carl Ritter are both regarded as the founders of modern geography as they established it as an independent scientific discipline.

Between 1799 and 1804, Humboldt travelled extensively in the Americas, exploring and describing them for the first time from a non-Spanish European scientific point of view. On these travels, along with French explorer Aimé Bonpland, he traversed thousands of miles through some of the most difficult and little-known places on Earth, to include identifying the source of the Orinoco River and in 1802 climbing the highest mountain in Ecuador to a height of 19,286 feet, at the time a world record altitude for a Westerner. His description of the journey was written up and published in several volumes over 21 years.
