Vischer, Friedrich Theodor (frēˈdrĭkh tāˈōdôr fĭshˈər) [key], 1807–87, German aesthetic philosopher. He taught at Tübingen, and later at Zürich and Stuttgart. Vischer was not only one of the most individual and independent critics of his century, but also a gifted author. His chief work is Ästhetik ; oder Wissenschaft des Schönen (6 vol., 1846–57). He also wrote the humorous and satirical Auch Einer [one more] (1879) and a parody of part of Goethe's Faust, as well as poems and numerous critical and philosophical works.
