English painter. He trained in London with Benjamin Wilson before going to Rome in 1757, where he studied with Anton Raphael Mengs. In Rome he met Charles Compton, 7th Earl of Northampton, who paid him an allowance and in Venice in 1763 introduced him to Edward Augustus, Duke of York. The Duke commissioned a conversation piece of himself and his travelling companions (version, 1764; London, Kew Pal., Royal Col.). The figures are awkwardly posed, but the polished elegance of each shows the influence of Mengs. In 1765 Brompton returned to London with Nathaniel Dance and established a good practice with small-scale works in the manner of Johann Zoffany, such as William Pitt, 1st Earl of Chatham (1772; Chevening, Kent), which exists in several versions. He also produced portraits on a larger scale, including the enormous Henry Dawkins with his Family (1773; Over Norton Hall, Oxon).
