DFWAJG 4 #1 March 22, 2007 From Smithsonian magazine. This month in history.. 130 years ago Maine teenager Chester Greenwood patents "ear mufflers" March 13, 1877. Greenwood, whose large ears make for uncomfortable ice skating, enlists his grandmother to cover connected wire loops with fur. The factory he starts wil produce 400,000 earmuffs a year. Greenwood secures over 100 patents before his death in 1937. Quote Share this post Link to post Share on other sites
