John Green is an alias for Bradock Mead (ca. 1688-1757). Raised in Dublin, his brother Thomas, served as Lord Mayor of the city in 1758-9. While in Dublin, he published The construction of maps and globes (London: 1717). He also became involved with a plot to kidnap an heiress. He escaped, but others in his group were not so lucky. He came to London and took on the name Rogers and worked as an amanuensis.
He was active in London from at least the early 1720s to 1755. Later, as Green, he translated du Halde’s Description géographique de la Chine into English for the publisher Edward Cave. He also worked on Astley’s voyage collection. However, he fell out with both men. From the 1730s onward, he worked periodically with Thomas Jeffreys, Geographer to Frederick Price of Wales and later to King George III. In 1757, he committed suicide by jumping from a third-story window.
