Baby its cold outside
“Baby, Its Cold Outside” may have been the song running through 13 year old Chester Greenwood’s head one cold December day in 1873. To protect his ears while ice skating, he found a piece of wire, and with his grandmother’s help, padded the ends. In the beginning, his friends laughed at him. However, when they realized that he was able to stay outside skating long after they had gone inside freezing, they stopped laughing. Instead, they began to ask Chester to make ear covers for them, too. At age 17 Chester applied for a patent. For the next 60 years, Chester’s factory made earmuffs, and earmuffs made Chester rich.
