Who discovered Georgia O'Keeffe's early drawings and exhibited them at 291?

Alfred Stieglitz exhibited Georgia O'Keeffe's early drawings at 291.

In 1916, O'Keeffe's friend Anita Pollitzer showed a selection of her charcoal abstractions to Stieglitz, the influential photographer and gallery owner. Stieglitz arranged for the drawings to be shown at his New York gallery, 291.

The exhibition helped bring O'Keeffe to the attention of the American avant-garde. Stieglitz continued to promote her work and organized many exhibitions of it. Their relationship later became romantic, and they married in 1924.

The word “discovered” is convenient shorthand, but it does not mean Stieglitz created O'Keeffe's style. She had already developed the drawings independently. His role was to recognize, exhibit, and promote work she had made before their professional association.
