Photographer, publisher and gallery director, Alfred Stieglitz was a central figure in the development of American art and photography.  Seventy-three of Stieglitz's finest photographs have been selected for publication in this book.  They span Stieglitz's entire career: his early European studies from the 1800s and 1890s; his views of New York City from the turn of the century; the protraits of the many artists and writers he supported; the extended portrait of Georgia O'Keefe; his photographs of clouds, the Equivalents; and his final studies of New York City and Lake George from the 1920s and 1930s.
