Alfred Stieglitz is undoubtedly one of the most significant contributors to the history of photography. He contributed not only scientific and artistic photographic studies, but also introduced modern art to America and furthered the theory of photography as art. Stieglitz was born in Hoboken, New Jersey on January 1, 1864.The renowned photographer Stieglitz first studied photochemistry with Hermann Wilhelm Vogel at the Technische Hochschule in Berlin, from 1882-1886, and took his first photographs in 1883. He continued to travel and photograph in Germany, Austria, and Switzerland until 1890, when he returned to New York City. From 1890 to 1895 he was a partner in a photogravure firm. During this time he concentrated on photographing the streets of New York City. In 1894, Stieglitz travelled to Europe and was elected a member of the Linked Ring, a pictorialist society in London. In 1902, Stieglitz founded the Photo-Secession Movement which attempted to prove that pictorialist photography was a fine art form. From 1903 to 1917, Stieglitz was publisher and director of Camera Work magazine. The graphic section was run by Edward Steichen (1879-1973). In 1905, Stieglitz opened the Little Galleries of the Photo-Secession "291" on Fifth Avenue in New York City with Steichen. Along with the other original members, Gertrude Kasebier and Clarence H. White, they formulated their mission to secede from conventional expectations and explore the creative potential of photography from both a theoretical and scientific point of view. Needing space to gather, work and exhibit, the gallery was open to and exhibited such paintings by Cezanne, Picasso, Braque and Matisse. The gallery was also a gathering place for writers, philosophers and musicians. Georgia O'Keeffe and Stieglitz began their relationship in 1917; she eventually became his wife. Over the next twenty years together, Stieglitz made more than 300 images of O'Keeffe. Accomplished photographic scientist, photographer, gallery owner, art dealer, collector and writer, Stieglitz was inducted into the International Photography Hall of Fame and Museum in 1971. Throughout his life, until his death in 1946, he fought for the art and science of photography. A great, fearless fight. And if he were alive today he would still be fighting. Photography as a respected art form is still not accepted by some today.
