Waltham Watch Company
Framingham is known for the Framingham Heart Study, as well as for the Dennison Manufacturing Company, which was founded in 1844 as a jewelry and watch box manufacturing company by Aaron Lufkin Dennison, who became the pioneer of the American System of Watch Manufacturing at the nearby Waltham Watch Company. His brother Eliphalet Whorf Dennison developed the company into a sizable industrial complex which merged in 1990 into Avery Dennison, with headquarters in Pasadena, California, and active corporate offices in the town.
