he Humboldt University of Berlin (German Humboldt-Universität zu Berlin) is Berlin's oldest university, founded in 1810 as the University of Berlin (Universität zu Berlin) by the liberal Prussian educational reformer and linguist Wilhelm von Humboldt, whose university model has strongly influenced other European and Western universities. From 1828 it was known as the Frederick William University (Friedrich-Wilhelms-Universität), later also as the Universität unter den Linden. In 1949, it changed its name to Humboldt-Universität in honour of both its founder Wilhelm and his brother, naturalist Alexander von Humboldt.
The first semester at the newly founded Berlin university occurred in 1810 with 256 students and 52 lecturers in faculties of law, medicine, theology and philosophy under rector Theodor Schmalz. The university has been home to many of Germany's greatest thinkers of the past two centuries, among them the subjective idealist philosopher Johann Gottlieb Fichte, the theologian Friedrich Schleiermacher, the absolute idealist philosopher G.W.F. Hegel, the Romantic legal theorist Savigny, the pessimist philosopher Arthur Schopenhauer, the objective idealist philosopher Friedrich Schelling, cultural critic Walter Benjamin, and famous physicists Albert Einstein and Max Planck. Founders of Marxist theory Karl Marx and Friedrich Engels attended the university, as did poet Heinrich Heine, German unifier Otto von Bismarck, Communist Party of Germany founder Karl Liebknecht, African American Pan Africanist W. E. B. Du Bois and European unifier Robert Schuman, as well as the influential surgeon Johann Friedrich Dieffenbach in the early half of the 1800s. The university is home to 29 Nobel Prize winners.
The structure of German research-intensive universities, such as Humboldt, served as a model for institutions like Johns Hopkins.
