Thomas Lawrence was the leading British portrait painter of the Regency era and the most fashionable portraitist in Europe following the death of Reynolds. Appointed Principal Painter to King George III at 23, he painted nearly every significant European monarch, general, and statesman of his era. His portrait Pinkie (1794), showing the young Sarah Barrett Moulton in a windswept white dress against a stormy sky, became one of the most beloved images in English portraiture — often paired with Gainsborough's Blue Boy.
