For the last 39 years, the US state of Maine has marked the first day of winter by celebrating Chester Greenwood Day, in honor of the 15 year old who invented the modern day earmuff, all the way back in 1873. An avid ice skater, Chester Greenwood would often find that he’d be forced to cut his fun short, due to his ears becoming too cold. As he was allergic to wool caps, Greenwood approached his grandma and asked her to sew together some ‘ear muffs’ made of wire, beaver fur and cloth. Although he was initially mocked for his strange ear protectors, Greenwood’s friends soon realized that they served a real purpose, and before long everyone was wearing them. As an adult, Greenwood built a small factory and began mass-producing his ear protectors. When WW1 broke out, Greenwood’s factory was enlisted to provide earmuffs for thousands of troops, and by 1936 the company was producing 400,000 pairs a year.
