Robert Grosvenor, 1st Marquess of Westminster, (22 March 1767 – 17 February 1845) was the son of the 1st Earl Grosvenor, whom he succeeded in 1802 as 2nd Earl Grosvenor. He was created Marquess of Westminster in 1831. He was an English Member of Parliament (MP) and an ancestor of the modern-day Dukes of Westminster. Grosvenor continued to develop the family's London estates, he rebuilt their country house, Eaton Hall in Cheshire where he also restored the gardens, and built a new London home, Grosvenor House. He maintained and extended the family interests in the acquisition of works of art, and in horse racing and breeding racehorses. Personal life Robert Grosvenor was born on 22 March 1767 in the parish of St George Hanover Square, London. He was the third son and the only surviving child of Richard Grosvenor, 1st Earl Grosvenor and Henrietta, Lady Grosvenor, and was initially known as Viscount Belgrave. He was educated at Westminster School, Harrow School, and Trinity College, Cambridge, where he graduated MA in 1786. In addition to his formal education, William Gifford acted as his private tutor. Gifford accompanied Grosvenor when the latter undertook his Grand Tour between 1786 and 1788. Gifford described him as a "most amiable" and "accomplished" pupil. On 28 April 1794 Grosvenor married Eleanor, the only child of Sir Thomas Egerton (later the 1st Earl Wilton). They had four children; in 1795 Richard, Lord Belgrave, who succeeded his father; in 1799 Thomas, who became the 2nd Earl of Wilton on the death of his grandfather; in 1801 Robert, later the 1st Baron Ebury; and finally a daughter, Amelia, who died in her early teenage years. Political and public life Grosvenor was elected as MP for East Looe in 1788 and served this constituency until 1790; during this time he was appointed a Lord of the Admiralty. His first speech in the House of Commons of Great Britain contained a quotation from the ancient Greek orator Demosthenes, which led to the satirist Peter Pindar calling him "the lord of Greek". In 1790 he was elected as MP for Chester and continued to serve in this seat until 1802. Between 1793 and 1801 he was a commissioner of the Board of Control. He raised a regiment of volunteers from the city of Westminster to fight against France and in 1798 was appointed its major-commandant. When his father died on 5 August
