There is a great story about 96 year old Julius Shulman in October's Dwell Magazine (sorry, just got a moment to read this 2 month old mag.) He was (& is still active) a great architectural photographer w/many iconic images.

I have a couple of his how to books on architectural photography & they are very useful despite being somewhat dated. (There is one where he refers to the Canon AE-1 as an amazing space age camera). The interesting thing about him is that he was largely self taught & was recognised early as having a good eye. Ezra Stoller is another good one to look at for buildings.
