Bernard Zimmerman, FAIA, wore many hats in the Southern California architectural community. He was an architect, planner, educator, preservationist, mentor, and curator. But friends and colleagues say he will be best remembered as the conscience of his profession, a passionate advocate for architecture and design who wasn’t shy about voicing opinions about what he loved and what he loathed. Zimmerman died June 4 at his Los Angeles home after a long illness. He was 79.
