Brothers Russell and Leil Gray incorporated Gray Company in April 1926 during the height of the “Roaring Twenties.” The Gray brothers launched the company to manufacture and market an air-powered, portable lubricator Russell invented while working as a parking lot attendant. His big idea emerged as he fumbled with a manual grease gun in freezing Minneapolis temperatures that turned grease into thick sludge. The Gray brothers had a “start-up” and we began operations at 120 South Tenth Street in Minneapolis.
