At 15 years old Chester Greenwood went ice skating on a pond near his home in Farmington Maine. It was so cold his ears nearly froze off. The next afternoon he covered his ears with a woolen scarf that proved to be too itchy and heavy. The next day he bent
some wire into ear shaped loops and asked his grandmother to sew fur around them. It worked perfectly, so much so that he soon received requests from neighbors and friends for a pair of "muffs for the ears". Ultimately he patented his design and founded the
Greenwood Ear Protector Factory in 1877. He became extremely wealthy supplying them to U.S. Soldiers during World War I. 

There you have it Made In the Good Ole USA!
