Ilse Langner published her first book of poems at age 14, and inherited from her father a passion for literature and the world of antiquity. She moved from her native Breslau to Berlin to become a journalist in the 1920s. In 1929, she published her first play, Frau Emma kämpft im Hinterland (Mrs. Emma Fights in the Rear), an anti-war piece that made her famous. Die Heilige aus USA (The Saint of the USA), a biographical play about Mary Baker Eddy, founder of the Christian Science movement, was probably her most successful play. Many of her works focused on the lives of women and raised issues such as women's rights. Her 1933 comedy Amazonen (Amazons) was banned by the Nazi regime that had just come to power and Ilse Langner was then effectively silenced until after World War II. After the war, she was able to publish a large number of novels, plays, essays, and travel articles. She undertook a lecture tour around the world in 1966-1967 for the Goethe Institute to represent German writers.
