Augustin Toussaint was the son of Louis Toussaint, a London based jeweler and enameler. In 1768 he was apprenticed as enamel painter to the renowned enameler and gold chaser George Michael Moser for the enormous fee of 200 guineas.
Augustin Toussaint's works were exhibited at the Royal Academy (1775-88) and are recorded on watches signed Emery, Perigal, the present watch and a watch case in the Victoria & Albert Museum (inv. no. 1065-1855).
The neoclassical grisaille on a brown ground enamel decoration enjoyed great popularity in late 18th century London.
