A recent post about a curious-looking implement with the Duluth Coolerator brand name led me down a surprisingly challenging research path. When did people (in Duluth and elsewhere) stop using “ice boxes” and start using modern electric refrigerators?
The Duluth Show Case Company, doing business as Duluth Store Equipment or simply Duluth Equipment, was a maker of display cabinets using the “Duluth Method” or “Duluth Unit System of Sectional Store Furniture.” Read the ad copy to determine what that might mean.
The Coolerator Company manufactured refrigerators and sold them in every state and 74 foreign nations. It began in 1908 as the Duluth Showcase Company, a manufacturer of store fixtures in Downtown Duluth. Operations moved to 50th Avenue West and Wadena Street in 1921. The focus switched to iceboxes in 1928 and the business was renamed Duluth Refrigerator Company. It became the Coolerator Company in 1932 and opened a manufacturing plant in New Duluth in 1935.
