Horace Pitt-Rivers, 6th Baron Rivers

Horace Pitt-Rivers, 6th Baron Rivers (12 April 1814 – 3 March 1880), known as Horace Beckford until 1828 and Hon. Horace Pitt from 1828 until 1867, was a British peer and army officer.

He was born on 12 April 1814 in London, the younger son of Horace Beckford and his wife Frances, and was baptised on 11 May at St George's, Hanover Square. Beckford, as he then was, was educated at Harrow School from 1824 to 1826 and then at the Royal Military College, Sandhurst. In 1828, his father inherited the Pitt estates and the title of Baron Rivers by a special remainder, and adopted the surname of Pitt for his younger son.

On 27 February 1830, Pitt (as he now was) bought a cornetcy in the Royal Horse Guards vacated by Viscount Fordwich. On 6 July 1832, he bought a lieutenancy vacated by the Hon. George Weld-Forester and on 11 November 1836, a captaincy vacated by Lord Elphinstone.

On 10 April 1845, at Brighton, he married Eleanor Sutor. No children were born of the marriage. She was a courtesan of the Regency period under the name of "Nellie Holmes", and had lived with Pitt before the marriage. (See Harriette Wilson for context.) They agreed to separate in 1846.

Pitt was breveted a major in the Army on 9 November 1846, and purchased a substantive majority vacated by Weld-Forester on 2 September 1853, receiving a brevet lieutenant-colonelcy from the same date. He retired from the Army on 21 April 1854, having been forced to sell his commission due to his gambling and horse-racing debts. He then spent a number of years in hiding from his creditors, living at Soval on the Isle of Lewis and then from 1858 at Kilninver. He attempted to obtain a divorce from his wife, but without success; the House of Lords held that he had not become domiciled in Scotland, and was therefore unable to take advantage of the more liberal Scottish divorce laws.
