William Barker (June 29, 1770 - April 19, 1805) was an engraver active in Philadelphia un the late 18th and early 19th centuries. Barker was born in Philadelphia, the son of Elihu Barker (17?? - 1792). Both father and son worked for the firm of Mathew Carey (1760 - 1839) and engraved maps for Carey's American Atlas, considered the first general atlas published in America. He appears in Philadelphia directories for 1795 - 1796 and 1800 - 1809. His business may have been carried on by a son of the same name, but it is unclear.
