Which photographer introduced Georgia O'Keeffe's work in a 1916 exhibition?

Alfred Stieglitz introduced Georgia O'Keeffe's work in a 1916 exhibition.

Stieglitz displayed a group of O'Keeffe's charcoal abstractions at his New York gallery 291 in 1916. The exhibition was arranged without O'Keeffe's prior approval, but it brought her work to the attention of influential members of the American avant-garde.

The drawings represented a bold departure from the academic realism O'Keeffe had studied earlier. Their sweeping lines and abstract forms helped establish her as an important emerging modernist, even before her best-known flower paintings.

Stieglitz was both a photographer and an influential gallery owner, publisher, and advocate for modern art. His support helped launch O'Keeffe's career, while his later photographs of her became an important part of the public story surrounding their relationship. Their professional connection preceded their marriage by eight years.
