Which New York art dealer first exhibited Georgia O'Keeffe's work in 1916?

Alfred Stieglitz first exhibited Georgia O'Keeffe's work in 1916.

Stieglitz was a photographer, publisher, and influential New York art dealer who operated the gallery known as 291. Anita Pollitzer showed him some of O'Keeffe's charcoal abstractions, and he displayed them at 291 without first obtaining O'Keeffe's permission. The exhibition introduced her work to an important modernist audience.

O'Keeffe initially objected to the unauthorized showing, but Stieglitz soon became a major advocate for her art. He presented her work in several exhibitions and later became her husband. Their relationship connected O'Keeffe to a broad network of American and European modernists.

The answer is sometimes confused with 291, which was the gallery rather than the dealer. Stieglitz's role also differed from that of a museum curator: he actively selected, promoted, and sold modern art through his galleries and publications.
