  • In December, we put together a display on the life of Maine inventor Chester Greenwood, who had four patents in his lifetime. The most famous of these was for his design revolutionizing earmuffs. He was a lifelong engineer, innovator, and a pillar of the community. We also put up a research guide on Greenwood for our library’s website (right).
