What's more interesting is to read about the photographers in his time frame. Exploring the period of the '30's for example is very interesting. You have many people developing their "styles" and exploring the world they lived in. Strand, Evans, Weston, Adams, Stieglitz, and the list is long. There are many many women also that don't make the "A" list.
Steichen, Stieglitz, and Strand is often given as the 20th Century's greatest photographers. It's the "A" tier of photographers. Edward Weston, Ansel Adams, Minor White and others are on the 2nd tier.
My favorites are Edward Weston, Paul Strand, HCB, Brett Weston, W.E. Smith, in no particular order.
