In 1874 Brentano published his major work, Psychology from an Empirical Standpoint. From 1874 to 1895 he taught at the University of Vienna, Austria-Hungary. Among his students were Edmund Husserl, Sigmund Freud, Tomáš Masaryk, Rudolf Steiner, Alexius Meinong, Carl Stumpf, Anton Marty, Kazimierz Twardowski, and Christian von Ehrenfels and many others (see School of Brentano for more details). While he began his career as a full ordinary professor, he was forced to give up both his Austrian citizenship and his professorship in 1880 in order to marry Ida Lieben (Austro-Hungarian law denied matrimony to persons who had been ordained priests even if they later had resigned from priesthood), but he was permitted to stay at the university only as a Privatdozent. After the departure of Twardowski back to Lwów and the death of his wife in 1894, Brentano retired and moved to Florence in 1896, where he married his second wife, Emilie Ruprecht, in 1897. He transferred to Zürich at the outbreak of the First World War, where he died in 1917.
