Alfred Stieglitz was an American photographer and modern art promoter. He was born in Hoboken, New Jersey in 1864 and died in 1946. He is considered one of the most important figures in the history of photography and played a major role in promoting photography as a fine art form.

Stieglitz began his career as a photographer in the late 19th century, and over the course of his career, he experimented with various photographic techniques and styles. He is known for his photographs of New York City and for his portraits of notable figures such as Georgia O'Keeffe, whom he later married.

In addition to his work as a photographer, Stieglitz was also a major advocate for the acceptance of photography as a legitimate art form. He founded the Photo-Secession movement in 1902, which sought to promote photography as fine art, and later founded the gallery "291" in New York City to showcase the work of photographers and other modern artists.

Stieglitz's work and his promotion of photography as an art form had a significant impact on the medium and on the art world more broadly. His work continues to be exhibited and studied in museums and galleries around the world.
