You don't have to be a Rockefeller to collect art. Herb Vogel was a postal clerk. Dorothy Vogel was a librarian. With their modest means, the couple managed to build one of the most important contemporary art collections in history. The Vogels shared passion and disciplines, defied stereotypes and redefined what it means to be an art collector. By Megumi Sasaki.
