Career
Active initially in Dublin, around 1747 he settled in London, managing a business at Battersea for the enamelling of china in colours by a process which he had devised. The articles produced were ornamented with subjects chiefly from Homer and Ovid. After a period of success the business folded on the bankruptcy of its chief proprietor, Stephen Theodore Janssen, Lord Mayor of London for 1754-1755.
Brooks stayed in London as an engraver and enameller of china.
Some of his pupils of Brooks worked as engravers in mezzotint, among them Michael Ford and James MacArdell.
