after visiting the Derby works granted him permission to incorporate the royal crown into the Derby backstamp, after which the company was known as 'Crown Derby'. In 1786, William Duesbury died, leaving the company to his son, William Duesbury II (1763–1796), also a talented director, who besides keeping the reputation of the company at its height, developed a number of new glazes and body types. Michael Kean William Duesbury II did not live to fulfil his promise: he died in 1797 at the age of 34 and the company was taken over by his business partner, an Irishman named Michael Kean, who later married Duesbury's widow. He seems not to have enjoyed good relations with the highly skilled workforce, and many eminent artists left. Others however produced good work under his management, including Moses Webster, a flower painter who replaced Billingsley, Richard Dodson (who specialised in birds), George Robertson (land- and seascapes) and Cuthbert Lawton (hunting scenes). The best-known artist of this time was William Pegg, a Quaker, famed for his striking and idiosyncratic flower painting. He started in 1797 but his religious beliefs led him to the conclusion that painting was sinful and he left in 1800. He returned in 1813, but left again in 1820. Despite much good work, the Kean period was disruptive and the company suffered financially. William Duesbury III, born in 1790, son of William Duesbury II, took over the factory when he came of age, and Kean having sold his interest to his father-in-law, William Duesbury's grandfather, named Sheffield, the concern continued under the name of Duesbury & Sheffield. Robert Bloor In 1815, the factory was leased to the firm's salesman and clerk, Robert Bloor, and the Duesburys played no further part in it. Bloor borrowed heavily to be able to make the payments demanded but proved himself to be a highly able businessman in his ways of recouping losses and putting the business back on a sound financial footing. He also possessed a thorough appreciation of the aesthetic side of the business, and under him the company produced works that were richly coloured and elegantly styled, including brightly coloured Japanese Imari patterns, generally featuring intricate geometric patterns layered with various floral designs. These designs proved extremely and lastingly popular, and Derby continued to thrive. In 1845, however, Bloor died, and after three years under Thomas Clarke, the Cockpit Works were sold and the
