The Gentleman’s Magazine was founded by Edward Cave (1691-1754) in 1731, a periodical which regularly featured maps from 1736 engraved by Emanuel Bowen, Thomas Bowen, John Gibson, Thomas Jefferys and others. Cave, who used the pseudonym Sylvanus Urban, was a friend of Samuel Johnson who wrote parliamentary reports for the magazine. Cave died on 10th Jan 1754 and his estate passed to his sister Mary Henry, his brother-in-law David Henry, and his nephew Richard Cave, who retained control of the magazine until 1778.
