Benjamin Willard (1743-1803), was the eldest of the four famous Willard brothers who were clock makers in Massachusetts. He began his own business after purchasing land in Grafton, Massachusetts in 1764.
Seven years later, Willard expanded his business to Roxbury where he worked until 1784, before returning to Grafton. For a discussion of Benjamin Willard, see Edwin A. Battison and Patricia E. Kane, The American Clock 1725-1865, pp. 54-55.
