Andreas Henry Groth (fl. 1740-55)
Groth was appointed enamellist to King George II...
Very little biographical information is available on the artist Groth, although he held an important appointment at court as appointed enamellist to George II (1741). Two portraits by him appeared in Horace Walpole’s sale of the contents of Strawberry Hill, showing that he was also a copyist in enamel, making smaller versions of oils by the fashionable portraitists Charles Jervas and Charles-Andre Vanloo.
His proficiency as a portrait painter from life can be seen in the family group of enamels by Groth, which appear to have been commissioned in 1753 and this may have been to celebrate the marriage of Thomas Edwards to Elizabeth Reveley in that year. In 1978, Christie’s sold a portrait of Thomas Edwards’ wife, Elizabeth Reveley (spelt ‘Riveley’ on the enamel), also dated 1753. The present enamel would appear to fall into that category, although sadly the sitter is unknown. A portrait of an unknown lady at the National Trust property of Attingham Park, Shropshire shows that Groth painted in watercolour on ivory, as well as in enamel.
