After her film career Sacy von Blondel began a second career as an author.
In 1955 she received a teaching position from Cambridge.
In 1938 Sacy von Blondel moved to Paris, after which hardly anything was heard from her.
In 1932 she finally stopped acting and began to publish as a writer (books of poetry, prose, theater reviews). However, some of her work received very bad reviews.
