Which photographer and gallery owner championed Georgia O'Keeffe's early career?

Alfred Stieglitz championed Georgia O'Keeffe's early career. He exhibited her work in New York, published reproductions, and helped establish her reputation among American modernist artists and collectors.

Stieglitz first saw a group of O'Keeffe's abstract charcoal drawings after a friend showed them to him. He displayed them at his gallery in 291 without initially identifying the artist publicly. O'Keeffe objected to aspects of this presentation, but the exhibition brought important attention to her work.

Their professional relationship became intertwined with their personal relationship after they met in person. Stieglitz photographed O'Keeffe repeatedly and presented her as a major modernist figure. Although his support was important, O'Keeffe's later work demonstrates her own evolving interests, including flowers, city architecture, and the landscapes of New Mexico.
