Chester Greenwood Day celebrates earmuffs

As a teenager, Greenwood loved skating. But he experienced cold ears. So, he put beaver fur pads on a wire and invented the earmuffs. He soon founded first earmuffs factory. Later he patented many other inventions. December 21, the first day of winter, is the official Chester Greenwood Day, or simply Earmuff Day.
