Here is an article that caught my eye. (Many years ago I used to live in Farmington, Maine where Chester Greenwood is rather famous as a local hero.) Let’s give some publicity to a local hero who is still fondly remembered today.
From the University of Maine web site:
Fogler Library staff have created a LibGuide about Chester Greenwood, the inventor of the earmuffs from Farmington, Maine. The guide includes links to information about Greenwood’s personal life, his other inventions and the early earmuff manufacturing process.
