What was Georgia O'Keeffe's first husband and longtime artistic collaborator called?

Georgia O'Keeffe's first husband and longtime artistic collaborator was Alfred Stieglitz. He was a major American photographer, gallery owner, and advocate for modern art.

Stieglitz first encountered O'Keeffe's abstract charcoal drawings after a friend brought them to his attention. He exhibited the drawings in 1916 at his gallery, 291, without initially having met her. Their professional relationship developed into a personal one, and they married in 1924.

Stieglitz photographed O'Keeffe extensively, producing hundreds of portraits over many years. Those photographs helped shape public perceptions of her, although O'Keeffe later objected to interpretations that reduced her art to biography or symbolism. Stieglitz remained her husband until his death in 1946, while O'Keeffe continued to develop an independent career.
