Edward Hooker Ensign (August 18, 1818 - July 10, 1871) was an American map and print publisher based in New York during the middle part of the 19th century. Edward was born in West Hartland, Connecticut. Little is known of Ensign's training but he may have inherited his business from his father, Timothy Ensign, who was a map publisher active in New York. Ensign seems to have had a flair for partnerships and variously published with Humphrey Phelps, Horace Thayer, Thomas Fanning and Erastus Bridgeman, among others. His various imprints include 'Phelps and Ensign' (1841-1844), 'T. and E. H. Ensign' (1844-1848), 'Ensign and Thayer' (1849), 'Ensign, Thayer, and Company' (1850-1851), 'Horace Thayer and Company' (1852), and 'Ensign, Bridgman and Fanning' (1854-1863). It appears that father and son worked together for some time as well, publishing as either 'T. and E. H. Ensign' or 'Ensigns'. At least some of these companies maintained offices in both Buffalo and New York City.
