Henry Herbert - 10th Earl of Pembroke

English peer, politician and courtier who served as a Lord of the Bedchamber to King George III in 1769.

Herbert was the son of Henry Herbert, 9th Earl of Pembroke (1693-1743) and Mary FitzWilliam. In 1756 he married Lady Elizabeth Spencer (1737-1831), a daughter of the Duke of Marlborough, with whom he had two children. He is also known to have had several mistresses, one of whom bore him a child who was given the remarkable name Augustus Retnuh Reebkomp.

He was educated at Eton College, and was styled Lord Herbert until he succeeded to his father's earldom in 1749. He became a Lieutenant-General in the Army, later Colonel of the 1st Regiment of Dragoons. He became an authority on breaking cavalry horses and in 1755 built an indoor Riding School at Wilton House.

As his London townhouse, Herbert purchased 40 Queen Anne St, Marylebone which he used for entertaining during the "London season". In 1760 he was sent with his regiment to Germany to take part in the Seven Years' War as a Major-General in command of the Cavalry Brigade in Germany until the following year. In 1761 he wrote the British Army's manual on riding, Military Equitation: or A Method of Breaking Horses, and Teaching Soldiers to Ride, which had already reached a 4th edition by 1793, and his methods were adopted throughout the British cavalry.
