Chester greenwood, 5, of farmington, Maine, invented earmuffs in 1874.
The boy liked winter very much, but he did not seem to have a particular liking for woolly hats, which made his skin itch. However, if he doesn’t wear a hat, it will make his ears feel very cold in winter. Once, he came home from an ice rink, picked up a wire along the way, made a prototype of a modern ear mask from that wire, and asked his grandmother to sew fabric between the coils.
The boy’s idea was so successful that he was granted a patent for the earmuffs three years later. In honor of his service, Maine declared December 21 Chester greenwood day, and farmington held an annual earmups parade.
More than 100 years ago, there was a young man named Humphrey du Porter in the United Kingdom who was hired by others to guard a steam engine. His task is to release the steam whenever the joystick of the steam engine falls. The child is so active that it is difficult for him to sit beside a machine for a long time, so he stares at the steam motor and gets his brains.
