Jeanne Robert Foster (née, Julia Elizabeth Oliver; March 10, 1879 – September 22, 1970) was an American occultist, Theosophist,[1] and poet from the Adirondack Mountains.

Professor Charles Townsend Copeland of Harvard was her personal instructor for three years and was a strong influence.

In 1913, the year of the Exhibition of Modern Art in New York, she wrote an article[4] featuring Cézanne, Picasso, Derain, Seurat, and other modernists.

[5] In 1915, Foster met English occult writer Aleister Crowley, attracted by his connection to black magic.

[2] From this period she traveled in Europe, met important figures of modernism, and collaborated with the collector John Quinn on building up his contemporary art collection.

[citation needed] She loved Maine and spent time at a cottage there with her sister, Mrs. Theodore H. Smith of Detroit.
