Gustav Teichmuller

Gustav Teichmüller (November 19, 1832 – May 22, 1888) was a German philosopher. His works, particularly his notion of perspectivism, influenced Friedrich Nietzsche's philosophy. Teichmüller was born in Braunschweig in the Duchy of Brunswick. He received a classical education and studied philosophy in Berlin and Tübingen. He taught as a professor at the Basel University (since 1868) and the Imperial University of Dorpat (since 1871). He died in Dorpat, Russian Empire (now Tartu, Estonia). After his father's death, Teichmüller worked as a tutor and completed his doctorate in Halle in 1856. He later taught Greek and German, married, and became an adjunct lecturer at the University of Göttingen. His student Rudolf Christoph Eucken became an important protégé. Teichmüller's personalism is described as a version of neo-Leibnizianism and Christian personalism, opposing positivism and evolutionism. His philosophical works cover Aristotle, the history of concepts, and the divide between the real and apparent world.
