Chester GreenwoodDied 5 Jul 1937 at age 78 (born 4 Dec 1858).American inventor and manufacturer of earmuffs, which, while a teenager, he designed and patented (U.S. No.188,292 issued 13 Mar 1877). He had experienced very uncomfortable cold ears while skating in winter, and solved his problem with beaver fur pads on a wire frame. By his mid-twenties, he had a factory and 11 workers producing Greenwood Champion Ear Protectors in his hometown of Farmington producing 50,000 earmuffs yearly. Distribution grew to 400,000 pairs by the year he died. He patented many other inventions. In 1977, the Maine state legislature officially declared 21 Dec, the first day of winter, as the annual Chester Greenwood Day. His hometown celebrates with a parade in early December.«[Image: Greenwood wearing the earmuffs from a promotional photo.] |
