Michael 'Angelo' Rocker (1746-1801) was taught engraving by his father and drawing by Paul Sandby, who is said to have given him the name 'Angelo'. He worked on book illustrations, both drawing and engraving, and was chief scene painter at the Haymarket Theatre for many years. In 1770 he was elected A. R. A. (Associate of the Royal Academy). In 1788 he began extensive tours of Britain, including Essex, Norfolk, Suffolk, Somerset, Warwickshire, Worcestershire and Wales.
