I mentioned Todd Papageorge earlier. The memory got me out of my chair and over to my bookcase to find his book: Core Curriculum. I started to flip through it, then sat down and started re-reading it, which I'll now do -- from cover to cover.
If you're even remotely interested in the history of photography, especially street photography you should find this book fascinating. Todd covers Atget, Cartier-Bresson, Brassai, Walker Evans, Robert Frank, and Winogrand, with whom he used to walk the streets of New York and shoot street, along with asides on several others.
I just checked Amazon to see if the book's still available. You can get it for $1,227.10 (only 3 left in stock), or for $23.98 (23 used & new).
