Today, March 13 is National Earmuff Day to celebrate Chester Greenwood of Farmington, Maine. Greenwood invented earmuffs when he was 15 years old.

It was on March 13, 1877, he was awarded a patent for his invention. Earmuff Day is not to be confused with Chester Greenwood Day in Farmington which is on the first Saturday in December.

The story goes that Greenwood had big ears and after a day of ice skating in the cold he found a better way to keep ears warm with the earmuff.

On nationaldaycalendar.com Greenwood and his grandmother sewed tufts of fur between loops of wire and the earmuffs were born. To this day Farmington, Maine is known as the Earmuff Capital of the World.

Greenwood had other inventions too. He came up with a tea-kettle, variations of the steel-toothed rake, an umbrella holder for mail carriers and he introduced the first telephone systems to Farmington.
