Lot Essay
William Pitt the younger, Prime Minister of England, sat to Thomas Gainsborough in 1787, at the age of 27. Ellis Waterhouse notes that this work, which was perhaps completed by Gainsborough Dupont, was painted for the Marquess of Buckingham. He further notes that there are about twenty or so portraits of Pitt ascribed to the elder Gainsborough but that these are mostly by or after Gainsborough Dupont (E.K. Waterhouse, op. cit., pp. 85-6; and E. Waterhouse, Gainsborough, 1958, p. 85, under no. 545).
