George Sidney Shepherd NWS (1784–1862) was born in Finsbury, London, the son of a watchmaker and brother of the artist Thomas Hosmer Shepherd. He is thought to have attended Dr Monro's sketching academy and he exhibited at the Royal Academy from 1800. In 1807 he made studies for Britton’s ‘Architectural Antiquities of Great Britain’ and also illustrated Booth’s ‘Architectural Series of London Churches’ (1818) and Wilkinson’s ‘Londina Illustrata’ (1824–34). With brother, Thomas Hosmer Shepherd, he made views for Ackermann’s ‘Repository of the Arts’ in 1813.
He was one of the founding members of the New Water-colour Society in 1831 and from 1832 he exhibited at the Society of British Artists. He was twice widowed by the time of his death in 1861.
