William Emmett, architect and draughtsman, was the eldest son of Maurice Emmett (c.1646-1684). He was baptised at St. Margret's Church, Westminster. In 1702 Emmett produced a series of engravings of St. Paul's Cathedral, which were published from a house in New Street, London, owned by Emmett’s younger brother (also named Maurice). Emmett and his wife were painted by the Flemish painter, resident in London, Balthasar van Lemens (1637-1704). Lemens was also commissioned to produce religious paintings and a ceiling painting, depicting the nine muses, for Emmett’s house in Bromley.
