Meghan McCarthy's back page note explains, "I start work on every book with a bit of free association. For Earmuffs, I started doing searches on the internet-"unique inventors," odd inventions"-until ultimately I put in the word "kid inventors." That's when I read about Chester Greenfield, who was born in 1858. "Mary Bells of about.com wrote,A grammar school dropout, he invented earmuffs at the age of 15 (1873). While testing a new pair of ice skates, he grew frustrated at trying to protect his ears from the bitter cold...." Meghan McCarthy explains, "That's when I knew that Chester was going to be the topic of my next book.
The topic of the book led her to look for more information and the book starts off with an explanation of a few others that were associated with the invention of earmuffs. However, Chester is the one given credit for the invention. The story talks about his patent and explains what a patent is and how to get one. The people of Maine have even declared December 21 as Earmuff Day in his honor!

Just makes you wonder about all the things you don't know about!
