Who introduced Georgia O'Keeffe's abstract drawings at New York's 291 gallery in 1916?

Alfred Stieglitz introduced Georgia O'Keeffe's abstract drawings at New York's 291 gallery in 1916.

Anita Pollitzer showed O'Keeffe's charcoal drawings to Alfred Stieglitz, the influential photographer and gallery owner. Stieglitz exhibited them at his New York gallery, commonly called 291, in 1916. This was O'Keeffe's first public exhibition in New York and brought her work into the circle of American modernism.

Stieglitz was already known for promoting avant-garde European and American artists. His gallery had displayed works by figures such as Picasso, Matisse, and Cézanne. He recognized the force of O'Keeffe's simplified, abstract forms and became an important advocate for her career.

Pollitzer is a frequent alternative answer because she played the crucial role of bringing the drawings to Stieglitz. However, Stieglitz was the person who exhibited them. Their professional relationship later became personal: O'Keeffe and Stieglitz married in 1924.
