William Arden, 2nd Baron Alvanley was a British Army officer, peer and socialite, who was a friend of Beau Brummell and one of a close circle of young men surrounding the Prince Regent.

George Bryan "Beau" Brummell was an important figure in Regency England, and for many years he was the arbiter of British men's fashion. At one time, he was a close friend of the Prince Regent, the future King George IV, but after the two quarrelled and Brummell got into debt, he had to take refuge in France. Eventually, he died shabby and insane in Caen.
