Before the Cambro Food Bar, buffets were messy. You used chafing dishes with sterno fuel—open flames that were a fire hazard and dried out food quickly.

In 1951, Whitney St. John (the son) took a massive gamble. He began experimenting with . At the time, fiberglass was primarily used for boat hulls and car bodies, not food containers. The challenge was creating a material that was FDA-approved, non-porous, lightweight, and thermally efficient. John designed a modular, double-wall fiberglass food bar

Before the 1950s, foodservice operators relied heavily on metal: stainless steel pots, aluminum trays, and heavy, cumbersome galvanized buckets. While durable, metal had three fatal flaws: it was heavy, it conducted heat aggressively (burning hands and losing temperature rapidly), and it was noisy.
