Who was Georgia O'Keeffe's husband and an important early promoter of her work?

Georgia O'Keeffe's husband and important early promoter was Alfred Stieglitz.

Stieglitz was a pioneering American photographer, gallery owner, and advocate for modern art. He exhibited O'Keeffe's work at his New York gallery, 291, after receiving drawings from her friend Anita Pollitzer. Those exhibitions helped introduce O'Keeffe to the New York art world.

O'Keeffe and Stieglitz married in 1924. He photographed her extensively, producing hundreds of portraits over several decades. Their relationship was both personal and professional, although O'Keeffe developed an independent artistic reputation rather than simply remaining known as Stieglitz's subject.

Stieglitz is sometimes confused with other photographers associated with American modernism, including Edward Steichen and Paul Strand. Unlike those figures, Stieglitz was specifically O'Keeffe's husband and the early gallery advocate most closely tied to her public emergence.
