Who is your favourite B&W photographer?

I ask because Barnes and Noble is having a 40% off if you use a mastercard so I wanted to pick up a new photobook.

It can even be a monotone photographer such as Nick Brandt. Right now I'm deciding between the Planet Earth book, Nick Brandt, and Keith Carter.

What kind of photography? I love a book I recently got of George Hurrell's work, all B&W.

I'm mainly looking for a fine art one but all kinds are fine. I'm interested in anybody with a talent in B&W
