Hans Müller was attacked in Karl Kraus' play Die letzten Tage der Menschheit (de) (The Last Days of Mankind) and in his journal Die Fackel (The Torch).
He lived a lifetime - surprisingly open for that time - with his partner Nikolaus Schwarz as " couple " in Einigen on Lake Thun . When Müller died in 1950, Schwarz jumped into death because of love sickness..
His plays attained huge popularity and in the 10's he was the most played author at the noted Viennese Burgtheater.
Müller-Einigen went to Hollywood in the 1920s where several films were made from his scripts.
His brother was the author and critic Ernst Lothar (real name: Ernst Lothar Müller).
