Aaron Willard
Aaron Willard (October 14, 1757 – May 20, 1844) was an entrepreneur, industrialist, and clockmaker who worked at his Roxbury, Massachusetts, factory during the early years of the United States of America. While at the family farm at Grafton, Aaron Willard developed his career conjointly with his three brothers, who also became horologists (though Aaron's and his brother Simon's creations are the most significant).
