Nathaniel Shepherd of Dartmouth, Westport and New Bedford, Massachusetts.

Nathaniel Shepherd was born in Dartmouth on February 21, 1795 and died in New Bedford on October 28, 1882. He trained as a clockmaker under John Bailey II in Hanover, Massachusetts. It is currently thought that he started working on his own in 1816. In 1820, he formed a partnership with Ezra Kelley and worked with him until 1823 and then again together in 1833 through 1835.

Several tall clocks are known. One signed example is known with the place location listed as Westport. A similar Shepherd clock can be found in the Yale University Art Gallery collection, inventory no. 1964.54.2
