 Brentano has often been described as an extraordinarily charismatic teacher. Throughout his life he influenced a great number of students, many of who became important philosophers and psychologists in their own rights, such as Edmund Husserl, Alexius Meinong, Christian von Ehrenfels, Anton Marty, Carl Stumpf, Kasimir Twardowski, as well as Sigmund Freud. Many of his students became professors in different parts of the Austro-Hungarian Empire, Marty and Ehrenfels in Prague, Meinong in Graz, and Twardowski in Lvov (now Lviv), and so spread Brentanianism over the whole Austro-Hungarian Empire, which explains the central role of Brentano in the philosophical development in central Europe, especially in what was later called the Austrian Tradition in philosophy.
