Which New York art dealer represented Georgia O'Keeffe for much of her career?

Alfred Stieglitz represented Georgia O'Keeffe for much of her career.

Stieglitz was a pioneering photographer, gallery owner, and modern-art advocate. He first encountered O'Keeffe's abstract charcoal drawings after they were shown to him by the artist and educator Anita Pollitzer. In 1916, Stieglitz exhibited O'Keeffe's work at his New York gallery, 291, without initially having met her in person.

Their professional relationship became personal. Stieglitz and O'Keeffe married in 1924, and he photographed her extensively over many years. His galleries helped introduce her work to influential American audiences, while her paintings became an important part of his advocacy for modern art in the United States.

A common mix-up is to treat Stieglitz only as O'Keeffe's husband. He was also a major figure in American photography and exhibition history. His support was significant, but O'Keeffe later established an independent reputation and developed a body of work that ranged far beyond the early abstractions he first promoted.
