Picture a cold winter day in Farmington, Maine, back in the 1870s. Chilly air, frosty ears, brrr! A boy named Chester Greenwood decided freezing ears were a problem worth solving. He was only 15 years old when he first got the idea for better ear warmers.
A few years later, in 1877, Chester got a patent for his design. A patent is an official paper that says, "This idea belongs to me!" His patent called it an "improvement in ear-mufflers." Fancy, right? His drawings showed earmuffs with a hinge, so they could fit snugly around your head.
Here's a fun twist. People already covered their ears in winter before Chester came along. So he didn't invent the very first ear warmer. He made them better. And lots of great inventions work exactly like that. Somebody looks at an old idea and says, "I can fix that!"
Chester didn't stop at the idea, either. He built a factory and made earmuffs for real. His business gave people in his hometown jobs for about 60 years. That's one teenager's idea keeping a whole town busy, and keeping a whole lot of ears toasty.
So the next time your ears get cold, remember that a kid not much older than you helped warm them up.
Now here's a question for you: What everyday thing bugs you, and how would you invent a way to make it better?
