George Bryan "Beau" Brummell (7 June 1778 – 30 March 1840) 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 from complications of neurosyphilis in Caen.
Brummell was remembered afterwards as the preeminent example of the dandy, and a whole literature was founded upon his manner and witty sayings, which have persisted until today. His name is still associated with style and good looks and has been given to a variety of modern products to suggest their high quality.
