 Brentano left a huge number of unpublished manuscripts, including poetry and letters on a wide range of philosophical topics in his last domicile in Zürich and in his summer-residence in Schönbühel bei Melk; some manuscripts were probably left behind in Florence. After his death, Alfred Kastil and Oskar Kraus, who were students of Brentano’s former student Anton Marty in Prague, worked on the Nachlass, transferring a good part of it to Innsbruck. Their attempt to set up a Brentano-archive was supported by Tomas Masaryk, a former student of Brentano who had become founder and first President (from 1918 to 1935) of the Republic of Czechoslovakia. As a result, in 1932 many of the original manuscripts were moved to Prague where an archive was founded. Alas, due to the political turbulences that were to came over central Europe the project made it necessary to transfer the archive again. Substantial parts of the Nachlass were transferred to different places in the United States, some of it has later been brought back to Europe, especially to the Brentano-Forschungsstelle at the University of Graz, Austria, and the Brentano family archive in Blonay, Switzerland. (For a detailed history of Brentano’s Nachlass, cf. Binder (2013)).
