Born Ottilie Godefroy, she trained in Vienna, her native town and got her first engagement in Breslau. Later she worked with Max Reinhardt and Erwin Piscator in Berlin.
In 1904, Durieux married the Berlin Secession painter Eugen Spiro, and after their divorce, she remarried in 1910 the successful art dealer and editor Paul Cassirer, who committed suicide in a room next to the court room that pronounced her divorce.

In 1937 she moved to Zagreb (then in the Kingdom of Yugoslavia) where she remained until 1953.
