Here are some examples of bird painting by Louis Victor Gerverot (1747-1829), another French porcelain painter, who most likely knew Fidelle Duvivier while both were in the Netherlands, and who later collaborated with Duvivier in Staffordshire.
By July 1787 Gerverot was hired to make porcelain for John Turner of Lane End but the partnership was ended with the death of Turner a few months later. The only known surviving evidence of this enterprise is the famous porcelain “Gerverot beaker” which is said to have been made by Louis Victor Gerverot at the Turner factory, and was decorated, dated (July 1787), and signed by Fidelle Duvivier. It was once owned by Major William Tapp and suffered some damage during WWII air raids in the London area. After the war (1950) it was sold at auction and eventually came into the possession of the Antique Porcelain Company, NYC. Bevis Hillier illustrated it in Master Potters of the Industrial Revolution. The Turners of Lane End (London: Cory, Adams and Mackay, 1965), p. 44 (picture 28a). In 2010 it was bought by the British Museum (inv. 2010.8013.1), where it can be seen today.
