After marrying the Berlin businessman Alfred Schneider, she used her stage name Lena Stein-Schneider. Under this name she published songs, instrumentals and - as a woman a rare exception - also operettas. She often wrote the lyrics herself. Her pieces were dedicated to well-known people in Berlin's cultural life, in which Lena Stein-Schneider was well integrated, not least because, before the First World War, she ran a musical salon in which high-ranking social figures and nobility frequented.
