The links below connect to the Metropolitan Museum's Timelines of Art History and its great resources for selected photojournalists.:

1. Julia Margaret Cameron (1815 - 1879) "From the first moment I handled my lens with a tender ardour," she wrote, "and it has become to me as a living thing, with voice and memory and creative vigour." Her mesmerizing portraits and figure studies on literary and biblical themes were unprecedented in her time and remain among the most highly admired of Victorian photographs.

2. Nadar (1820 - 1920) was an eccentric who lived a highly theatrical life, but left a treasure of early portraits.

3. Eugene Atget (1857 - 1927) documented the architecture, gardens, courtyards and streets of Paris.

4. Alfred Stieglitz (1864 - 1946) in 1890 determined to prove that photography was a medium as capable of artistic expression as painting or sculpture. His gallery, publications and patronage of other photographers transformed the medium in America.

5. Paul Strand (1890 - 1976) his experimentation across many styles and techniques helped define the canon of early American modernism and set its premium on the elegant print.

6. Henri Cartier-Bresson (1908 - 2004) pioneered the small hand-held cameras and caught people at what he called "the decisive moment." Unfortunately, there are only six examples of his work.
