John Purdy (1773–1843) was an important English hydrographer. His work and influence extended beyond hydrography with the coinage of the term pharology, the study of modern lighthouses and their designs. Purdy's work Memoir, descriptive and explanatory, to accompany the New Chart of the Atlantic Ocean was adapted and improved; continuing to be released in its fifteenth edition fifty years after his death.
