13 March - Chester Greenwood received a patent for the invention of earmuffs in 1877

 

On March 13, 1877, Chester Greenwood, an American inventor from Farmington, Maine, received a patent for the invention of earmuffs. Greenwood came up with the idea for earmuffs at the age of 15 when he decided to find a solution to keep his ears warm while ice skating. He designed a pair of ear protectors made of wire with fur attached, and these earmuffs eventually became a widely used accessory for keeping ears warm in cold weather. Greenwood's invention earned him the nickname "the ear protector king," and his contribution is still recognized today as earmuffs remain a popular winter accessory.
