What they did

As chief chemist at Griffith Laboratories, Hall developed flash-drying of curing salts, antioxidant formulations that slowed rancidity in fats, and a vacuum-and-ethylene-oxide method for sterilising spices without destroying them.

Historical context

Spices carried bacteria and mould spores straight into cured meat. Heat sterilisation ruined their flavour; Hall's gas method did not.

Obstacles

Hired by telephone and turned away in person once his employer saw him, he built his career inside industrial laboratories rather than the universities that would not have him.

The legacy

He was granted dozens of United States patents across food chemistry and was inducted into the National Inventors Hall of Fame in 2004.
