December 7th is Earmuff Day or Chester Greenwood Day

Chester Greenwood (1858-1937) made his first pair of "ear protectors" when he was 15 years old. He was granted a patent in 1877 and established an entirely new industry in his hometown of Farmington, Maine, where he continued to refine the design and manufacture of what we now know as earmuffs. By 1918 he was making 216,000 pairs a year, and by 1932 checks and plaids were added to the standard black velvet covering.

Although Greenwood was involved in a number of other business ventures in Farmington and was granted his last patent—for a tempered steel lawn rake—only a few months before he died, it is for his ear protectors that he is primarily remembered. Farmington residents celebrate Chester Greenwood Day on the first Saturday in December (Greenwood was born on December 4) with a parade, flag-raising ceremony, and a foot race. Everyone is encouraged to wear earmuffs for the festivities, including pets.
