In 1873, Farmington teenager Chester Greenwood is said to have tired of freezing ears while skating and devised a simple remedy with wire, cloth, and beaver fur. He received a U.S. patent for his improved “ear-mufflers” in 1877, turning a cold-weather annoyance into a durable invention. Farmington mattered because Greenwood did not merely invent here; he built here, employing local workers and attaching his name to the town’s streetscape. Over time, the earmuff became both a product and a civic emblem, tying winter ingenuity to local industry and pride. Today the town still honors him with Chester Greenwood Day, proving that some inventions leave a warmer cultural afterglow than others.
