Philip Dormer Stanhope, 4th Earl of Chesterfield PC KG (22 September 1694 – 24 March 1773) was a British statesman and man of letters.
A Whig, Lord Stanhope, as he was known until his father's death in 1726, was born in London. After being educated at Trinity Hall, Cambridge, he went on the Grand Tour of the continent. The death of Anne and the accession of George I opened up a career for him and brought him back to England. His relative James Stanhope, the king's favourite minister, procured for him the place of gentleman of the bedchamber to the Prince of Wales.
In 1715 he entered the House of Commons as Lord Stanhope of Shelford and member for St Germans, and when the impeachment of the Duke of Ormonde came before the House, he used the occasion (5 August 1715) to put to proof his old rhetorical studies.
