Alfred Stieglitz (January 1, 1864 – July 13, 1946) was an American photographer and modern art promoter who was instrumental over his fifty-year career in making photography an accepted art form. In addition to his photography, Stieglitz is known for the New York art galleries that he ran in the early part of the 20th century, where he introduced many avant-garde European artists to the U.S. He was married to painter Georgia O'Keeffe.

Stieglitz was born in Hoboken, New Jersey, the first son of German-Jewish immigrants Edward Stieglitz (1833–1909) and Hedwig Ann Werner (1845–1922). At that time his father was a lieutenant in the Union Army, but after three years of fighting and earning an officer's salary he was able to buy an exemption from future fighting. This allowed him to stay near home during his first son's childhood, and he played an active role in seeing that he was well-educated. Over the next fifteen years the Stieglitzes had five more children: Flora (1865–1890), twins Julius (1867–1937) and Leopold (1867–1956), Agnes (1869–1952) and Selma (1871–1957). Alfred Stieglitz was said to have been very jealous of the closeness of the twins, and as a result he spent much of his youth wishing for a soul mate of his own.

Georgia Totto O'Keeffe (November 15, 1887 – March 6, 1986) was an American artist.

Born near Sun Prairie, Wisconsin, O'Keeffe first came to the attention of the New York art community in 1916, several decades before women had gained access to art training in America’s colleges and universities, and before any of its women artists were well known or highly celebrated. Within a decade, she had distinguished herself as one of America's most important modern artists, a position she maintained throughout her life. As a result, O’Keeffe not only carved out a significant place for women painters in an area of the American art community that had been exclusive to and is still dominated by men, but she also became one of America’s most celebrated cultural icons well before her death at age 98 in 1986.

Her abstract imagery of the 1910s and early 1920s is among the most innovative of any work produced in the period by American artists. She revolutionized the tradition of flower painting in the 1920s by making large-format paintings of enlarged blossoms, presenting them close up as if seen through a magnifying lens. In addition to this, O'Keeffe's depictions of New York buildings, most of which date from the same decade, have been recognized as among the most compelling of any paintings of the modern city. Beginning in 1929, when she first began working part of the year in Northern New Mexico—which she made her permanent home in 1949—O’Keeffe depicted subjects specific to that area. Through paintings of its unique landscape configurations, adobe churches, cultural objects, and the bones and rocks she collected from the desert floor, she ultimately laid claim to this area of the American Southwest, which earlier had been celebrated primarily by male artists; the area around where she worked and lived has become known as “O’Keeffe Country."
