Theodor Gomperz (March 29, 1832 – August 29, 1912), Austrian philosopher and classical scholar, was born at Brno (Brünn).
Gomperz studied at Brno and at Vienna under Hermann Bonitz. Graduating at the University of Vienna in 1867 he became privatdozent, and subsequently a professor of classical philology (1873). In 1882 he was elected a full member of the Vienna Academy of Sciences. He received the degree of Doctor of Philosophy honoris causa from the University of Königsberg, and Doctor of Literature from the universities of Dublin and Cambridge, and became correspondent for several learned societies.
Gomperz resigned his professorship at Vienna in order devote all his energy to his magnum opus Griechische Denker ("Greek Thinkers"), which first appeared in 1893.
He died in Baden bei Wien.
He supervised a translation of JS Mill's complete works (12 vols., Leipzig, 1869–1880), and wrote a life (Vienna, 1889) of Mill. His Griechische Denker: Geschichte der antiken Philosophie (vols. i. and ii., Leipzig, 1893 and 1902) was translated into English by L Magnus (vol. i., 1901).
