Chris Wroblewski published a fantastic book on street photographers from around the world a few years ago called "Smudgers" (apparently it's what the English used to call street photographers). The book is long out of print, but Chrish has just released a E Book for 5 Euro. If you can't get hold of the book (I was lucky enough to fluke one) then I'd recomment getting the E book..
