Who was Georgia O'Keeffe's husband and longtime artistic supporter?

Georgia O'Keeffe's husband and longtime artistic supporter was Alfred Stieglitz. Stieglitz was a pioneering photographer, gallery owner, and advocate for modern art in the United States.

He first exhibited O'Keeffe's work in 1916 at his New York gallery, 291. Their relationship became both personal and professional, and Stieglitz photographed O'Keeffe extensively over several decades. They married in 1924, although they spent substantial periods living apart.

Stieglitz's galleries helped introduce European modernism and new American art to the public. O'Keeffe eventually established her own artistic identity rather than remaining defined by his promotion. Their partnership is often discussed alongside the history of photography, modern painting, and the New York art world of the early twentieth century.
