Etcher, mezzotint and aquatint artist. Became the student of an unknown engraver in Worchester, against the wishes of his father. In a forty-year period he produced close to 400 plates executed after the masters of both old and modern schools. In 1789 the Duke of Bavaria granted him exclusive rights to create and publish engravings after the paintings in the gallery at Dusseldorf. This enterprise, with which his son Rupert helped considerably, had, on account of the continental war, disastrous consequences, and the artist was almost completely ruined. With the foundation of the British Institution in 1805 he was offered the position of Conservator and retained the position until his death. Green's technique is absolutely personal and his composition reveals at each instant some new surprise. Called, "an English Janinet" (Benezit). Named engraver to King George III.
