Canadian born Beulah Maude Durrant (her real name) studied in Berlin to be a concert pianist and was later driven from her adopted city San Francisco when her brother was tried and found guilty of a notorious murder. Around the turn of the century she published one of the first sex manuals before becoming an interpretive dancer. In 1918, she was involved in a sensational libel suit with many echoes of the Wilde trial, when she sued a British Member of Parliament for accusing her publicly of lesbianism and various other practices. (She was, in fact, a lesbian). Her last three decades were spent as a dance teacher. She passed away in Los Angeles in 1956.
