We love how willing folks have been to share their knowledge with us, and Dr. James Campbell goes above and beyond in this episode! Dr. Campbell is the head of the Architecture Department at the University of Cambridge, and Chair of Construction History Society. We poke a few holes in the prevailing historical narrative of hard hat history, revisit bowlers from a different perspective, and talk about hats in academia.

Check out Dr. Campbell's book, "Brick: A World History."
