of Middlesex 16 Nov. 1475. Edward IV showed him special favour and made him dean of the Chapel Royal, dean of the collegiate church of Bridgnorth (1471), prebendary of St. Mary's College, Leicester (2 Aug. 1472), dean of Windsor (1473), prebendary of Wells (1475–6), and bishop of Durham (October 1476). In 1483 he was nominated chancellor of the university of Oxford in place of the king's brother-in-law, Lionel Wydville, bishop of Salisbury. He died 29 Nov. 1483, and was buried beneath an elaborate monument in the chapel of St. Nicholas in Westminster Abbey.

DUESBURY, WILLIAM (1725–1786), china manufacturer, born 7 Sept. 1725, was son of William Duesbury, currier, of Cannock in Staffordshire. He first practised as an enameller at Longton in the same county, but in 1755 he moved with his father to Derby. At this time the Derby potworks on Cockpit Hill were held by Messrs. John and Christopher Heath, bankers in the town, while at the same time a French refugee, Andrew Planché, was making china figures in an obscure tenement in Lodge Lane. Duesbury learnt the art from Planché, and entered into an agreement with him and John Heath to establish a china manufactory. Soon after the Heaths failed, Duesbury, having cleared himself from the debts which their failure brought upon him, set up a china manufactory for himself in the Nottingham Road. This may fairly be called the first foundation of the Derby china manufactory. Duesbury managed to obtain a good staff of workmen and assistants, and the manufactory soon became prosperous and important, and the products extensively sought after. In June 1773 he opened a warehouse in London at No. 1 Bedford Street, Covent Garden, and had periodical sales by auction of his stock. In 1770 he purchased the works and stock of the defunct manufactory at Chelsea, in 1775 those of the manufactory of Bow, in 1777 those of Giles's manufactory, Kentish Town, besides others; he thus became the most important china manufacturer in the kingdom, and enjoyed the royal patronage. Duesbury died in November 1786, and was buried in St. Alkmund's, Derby. By his wife, Sarah James of Shrewsbury, he had several children, of whom William Duesbury, the eldest surviving son, succeeded to the proprietorship of the works. He was born in 1763, and the prosperity of the works reached its highest point shortly after he succeeded to them. He took into partnership an Irish miniature-painter named Michael Kean. Duesbury's health broke up early, and he died in 1796. By his wife, Elizabeth, daughter of William Edwards, solicitor, of Derby (who remarried the above mentioned Kean), he left three sons, of whom William Duesbury, born in 1787, inherited, but did not take part in the works, which in 1809 were disposed of to Robert Bloor [q. v.] The second son, Frederick Duesbury, became a well-known physician in London, and was father of Henry Duesbury, who practised as an architect in London, and died in 1872.

DUFF (Dubh, the Black) (d. 967), king of Celtic Alban (Scotland), son of Malcolm, succeeded, in 962, Constantine, son of Indulph, in whose reign Edinburgh (Dun Eden) was relinquished by the Angles, who had held it since Edwin of Deira (617–632) gave it its name. It now became a Celtic fort. In 965 Duff defeated Colin, the son of Indulph, supported by the abbot of Dunkeld and the chief of Athole at Drumcrub in Strathearn. Two years later Colin reversed this victory and expelled Duff, who, according to a later chronicle, was afterwards, when attempting to recover his kingdom, slain at Forres. His body was hidden under the bridge of Kinloss, and the sun did not shine till it was found and buried. An eclipse on 10 July 967 may have originated or confirmed this story.

DUFF, ALEXANDER, D.D., LL.D. (1806–1878), missionary, was born at Auchnahyle in the parish of Moulin, Perthshire, 26 April 1806. In his boyhood he came under deep religious impressions, and in his course of study in arts and theology at the university of St. Andrews was much influenced by Chalmers, then professor of moral philosophy. As soon as he finished his theological course, he accepted an offer made to him by the committee of the general assembly on foreign missions to become their first missionary to India. Ordained in August 1829, Duff proceeded on his way, and after being twice shipwrecked on the voyage, and losing all his books or other property, reached Calcutta in May 1830. After much consideration he determined to make Calcutta his base of operations, and to conduct the mission in
