What was the name of Georgia O'Keeffe's husband, who died in 1946?

Georgia O'Keeffe's husband, Alfred Stieglitz, died in 1946.

Stieglitz was born in Hoboken, New Jersey, in 1864 and became a leading advocate for photography as a fine art. He also promoted modernist painting and drawing through galleries and publications in New York.

He married O'Keeffe in 1924 and represented her work through exhibitions at his galleries. His death on July 13, 1946, ended their marriage but not O'Keeffe's artistic career; she moved permanently to New Mexico three years later.

Stieglitz's name is sometimes confused with other American modernists who were part of the same artistic era. Unlike Dove, Demuth, and Hartley, he was primarily known as a photographer, gallery owner, and promoter.
