[2] Hollmann attended the Gymnasium (school) in Graz and then progressed to the local university, emerging in 1956 with a doctorate in jurisprudence.
[7] Hollmann later reprised his The Last Days of Mankind for the 1980 Vienna Festival, with a cast that included Helmut Lohner, Peter Weck, Paulus Manker, Alexander Goebel [de] and Götz Kauffmann, and returned to the piece on various occasions.
A particular focus was in respect of contemporary theatre, including first productions of plays by Bertolt Brecht, Elias Canetti, Tankred Dorst, Rainald Goetz, Peter Handke, Elfriede Jelinek, Heiner Müller and Botho Strauss.
[8] It introduced an entirely new approach to artistic training,[10] and for many years Hollmann himself served as its president, until succeeded in that role by Heiner Goebbels in 2006.
He also gave public readings, focusing in particular on the writings of Elias Canetti, Karl Kraus und Heinrich Heine.
He was also a recipient of the Josef Kainz Medal from the city of Vienna and, in 2006, of the highest honour from the State of Hessen, the Goethe Award.
