Chester Greenwood (1858-1937) of Farmington, Maine
invented the earmuff in 1873, at the age of 15. He reportedly came up with the idea while ice skating, and had his grandmother sew tufts of fur between loops of wire. His patent was for improved ear protectors. He manufactured these ear protectors, providing jobs for people in the Farmington area, for nearly 60 years.
Chester also patented a tea kettle, a steel tooth rake, an advertising matchbox, and a machine used in producing wooden spools for wire and thread. He invented, but did not patent an umbrella holder for mail carriers. He no doubt invented many other items, but only patented the above mentioned items.
