...Alfred Stieglitz was suddenly 60 and one of the world's most celebrated photographers. Kidney stones made his nights restless. He passed the time by reading Ulysses. The divorce from Emmy was final. The following summer his daughter was discharged from the hospital to a summer house at Sagamore Beach. He proposed to Georgia; she declined.
By the fall Kitty had been returned to the sanitarium. Her doctor came to Alfred with a proposal. If he married O'Keeffe, they suggested, Kitty might come to a peace of mind that would aid her recovery. In light of these circumstances, Georgia accepted her boyfriend's proposal after considerable pressure was exerted.
...Georgia's health problems complicated their new union, restricting her to bed rest. She was only just beginning to get well when Stieglitz met 21-year old Dorothy Norman. The girl who incessantly hung around Alfred's gallery, asking question after question, was married to the son of the founder of Sears. Edward Norman was a deeply disturbed person who was mentally, physically and sexually abusive to his wife.
Stieglitz initially tried to put Dorothy's at an arm's length. By the time he really got to know her, she was pregnant with her first child, a daughter. Like Kitty, Dorothy was a Smith graduate. Georgia noticed her husband's admiration of the pregnant woman, and it upset her greatly. To appease O'Keeffe, Stieglitz tried to confine his expressions of love to secret letters. "I want to incorporate knowing you into my life," Dorothy wrote back, and in order to position herself as closely as possible to the photographer, commenced work on an article about Alfred that would become a book.
...When Georgia went off to a retreat, Stieglitz finally consummated the relationship with his young admirer. His descriptions of that moment are nauseating at best...
This consummation pushed Alfred in the other direction. Georgia was happiest in New Mexico, and Stieglitz endlessly complained about the time she spent there away from him. She felt his pull — "It is always such a struggle for me to leave him" — but New York was not her favorite place. "I think I would never have minded Stieglitz being anything he happened to be," she told a friend, "if he hadn't kept me so persistently off my track."
Even though Alfred thought nothing of cheating on his wife, he flew into a fury whenever he suspected that she might be unfaithful. The balance of their relationship was changing, however, as Stieglitz was increasingly financially dependent on his wife's flourishing artistic career. He was determined to improve his marriage.
Stieglitz still saw much of Dorothy, who had given birth to a second child. He photographed Dorothy Norman for the first time in 1930, when she was 25 years old. Alfred bought Dorothy a camera, and told her that he loved her. Each saw the relationship as a supplement to their marriage, and sought nothing more from one another. A friend wrote to Alfred that talking to Dorothy was like "talking to a mirror in which one didn't see oneself but someone else. She presents no problem, no burden or personality to be dealt with. One can be with her and at the same time alone with oneself."
"He was perhaps the most impressive person I have ever known," Dorothy wrote later. "Yet the greatness of what he expresses was in terms of how people must be non-possessive." Alfred Stieglitz demonstrated this principle by comparing his wife and his young girlfriend in a 1932 exhibition that was the talk of the art community....
In the days that followed Stieglitz's small funeral, Georgia called up Dorothy Norman. She told Dorothy to clear all her stuff from the gallery, commenting that she found Dorothy's relationship with her husband "absolutely disgusting." After Alfred's death, Georgia O'Keeffe lived forty more years.
