Anne Goldthwaite was an American painter and printmaker and an advocate of women's rights and equal rights. Goldthwaite studied art in New York City. She then moved to Paris where she studied modern art, including Fauvism and Cubism, and became a member of a circle that included Gertrude Stein, Henri Matisse, and Pablo Picasso. She was a member of a group of artists that called themselves Académie Moderne and held annual exhibitions.

Katherine Sophie Dreier was an American artist, lecturer, patron of the arts, and social reformer. Dreier developed an interest in art at a young age and was afforded the opportunity of studying art in the United States and in Europe due to her parents' wealth and progressive attitudes. Her sister Dorothea, a Post-Impressionist painter traveled and studied with her in Europe. She was most influenced by modern art, particularly by her friend Marcel Duchamp, and due to her frustration with the poor reception that the works received, she became a supporter of other artists. She was co-founder of the Society of Independent Artists and the Société Anonyme, which had the first permanent collection of modern art, representing 175 artists and more than 800 works of art. The collection was donated to Yale University. Her works were exhibited in Europe and the United States, including the 1913 International Exhibition of Modern Art.
