About Essex Industries
Essex Industries is a family-owned aerospace and defence manufacturer founded in St. Louis, Missouri in 1947, when Harold Guller returned from Second World War service and developed a radio noise filter for military aircraft in his father's basement. Now in its third generation under chief executive Evan Waldman, the company employs more than 400 people in St. Louis, Huntington Beach, California and Milford, Connecticut, designing and manufacturing platform controls and aircraft components, liquid oxygen and emergency breathing equipment, and intricate mechanical and electrical assemblies for fixed-wing aircraft, rotorcraft, land vehicles and other platforms.
