Duke Of NewcastleThe first Duke of Newcastle upon Tyne, William Cavendish (born 16 December 1593 - died 25 December 1676), was an English courtier and supporter of the arts. He was a renowned horse breeder, as well as being patron of the playwright Ben Jonson, and th intellectual group known as the Welbeck Circle.Despite spending the then enormous sum of £15,000 entertaining Charles I in 1634, he failed to gain a significant political post.

After the defeat at Marston Moor in July 1644, a battle fought against his advice, he went into exile in Europe.He returned to England after the 1660 Restoration; although created Duke of Newcastle in 1665, he remained on the fringes of the court, and became critical of Charles II.
