What were some of Margaret Anderson’s later life activities?

After moving to Paris in the 1920s, American editor, publisher, and writer Margaret Anderson turned over the editorial responsibilities of The Little Review to Jane Heap in 1924 and became a devotee of Armenian mystic George Ivanovitch Gurdjieff. She began a relationship with French opera singer Georgette Leblanc, with whom she also performed on a concert tour (Anderson was also a pianist). Anderson also wrote a three-volume autobiography: My Thirty Years’ War (1930), The Fiery Fountains (1951), and The Strange Necessity (1962). Among her other works is the posthumously published novel Forbidden Fires (1996).
