Who was Georgia O'Keeffe's husband and longtime art promoter?

Georgia O'Keeffe's husband and longtime art promoter was Alfred Stieglitz.

Stieglitz was an influential American photographer, gallery owner, and advocate for modern art. He first exhibited O'Keeffe's work at his New York gallery in 1916, helping establish her reputation among critics and collectors.

Their relationship developed over several years. Stieglitz began making photographs of O'Keeffe in 1917, and the extensive series became an important part of his photographic career as well as a record of their relationship. They married in 1924.

The couple maintained separate working lives and spent substantial periods apart. O'Keeffe increasingly found inspiration in New Mexico, while Stieglitz remained based in New York and Lake George. He died in 1946, after which O'Keeffe continued to shape her own public and artistic legacy.
