We were excited to see Catherine Opie name Andrew Cahan as one of the un-sung heroes of the photography world in Aperture's Photography As You Don’t Know It series. As a monograph collector, Ms. Opie was struck by Cahan's focus on Japanese monographs from the 1970's. From that point onward, she was hooked and they became fast friends.
Cahan has moved back to his hometown of Akron, Ohio and still seeks out the best in books by and for photographers.
