was put on the house in 1951. In 1777, he again began to exhibit his paintings at the Royal Academy, including portraits of contemporary celebrities, such as the Duke and Duchess of Cumberland. Exhibitions of his work continued for the next six years. About this time, Gainsborough began experimenting with printmaking using the then-novel techniques of aquatint and soft-ground etching. During the 1770s and 1780s Gainsborough developed a type of portrait in which he integrated the sitter into the landscape. An example of this is his portrait of Frances Browne, Mrs John Douglas (1746–1811) which can be seen at Waddesdon Manor. The sitter has withdrawn to a secluded and overgrown corner of a garden to read a letter, her pose recalling the traditional representation of Melancholy. Gainsborough emphasised the relationship between Mrs Douglas and her environment by painting the clouds behind her and the drapery billowing across her lap with similar silvery violet tones and fluid brushstrokes. This portrait was included in his first private exhibition at Schomberg House in 1784. In 1776, Gainsborough painted a portrait of Johann Christian Bach, the youngest son of Johann Sebastian Bach. Bach's former teacher Padre Martini of Bologna, Italy, was assembling a collection of portraits of musicians, and Bach asked Gainsborough to paint his portrait as part of this collection. The portrait now hangs in the National Portrait Gallery in London. In 1780, he painted the portraits of King George III and Queen Charlotte and afterwards received other royal commissions. In February 1780, his daughter Molly was married to his musician friend Johann Christian Fischer, to Gainsborough's dismay, as he realized that Fischer was forming an attachment to Molly while carrying on flirtation with Peggy. The marriage between Molly and Fischer only lasted 8 months due to their discord and Fischer's deceit. In 1784, Principal Painter in Ordinary Allan Ramsay died and the King was obliged to give the job to Gainsborough's rival and Academy president, Joshua Reynolds. Gainsborough remained the Royal Family's favorite painter, however. In his later years, Gainsborough often painted landscapes. With Richard Wilson, he was one of the originators of the eighteenth-century British landscape school; though simultaneously, in conjunction with Reynolds, he was the dominant British portraitist of the second half of the 18th century. William Jackson in his contemporary essays said of him "to his intimate friends he was sincere and honest and that his heart was always
