On this day in 1778, George Bryan Brummell (known as Beau Brummell) was born in Downing Street London. His father was private secretary to the prime minister, Lord North, and his family was very upwardly mobile, living at The Grove, in Donnington, Berkshire. In 1786 George was sent to Eton College. From the Oxford Dictionary of National Biography:
He was also popular among fellow students for his wit, refinement, and a fascination with matters of dress and poise which defined his adult life and, as a schoolboy, earned him the sobriquet Buck Brummell.
Brummell went to Oxford for one term before inheriting a fortune on his father’s death. He met George, prince of Wales at Whig society balls held at Eton and they became close. Brummell was offered a cornetcy in his personal regiment, the 10th hussars, and was promoted to captain. He wasn’t much of a soldier and spent most of his time accompanying the prince to social events.
He became a leading member of London society, moving to 4 Chesterfield Street, Mayfair and holding many social occasions for the fashionable elite and aristocracy including the Prince. Oxford DNB:
The years between Brummell’s move to Chesterfield Street and his departure from England in 1816 witnessed the apogee of the fashion for dandyism of which Brummell was the leading exponent. The culture was characterized by its reaction against the excessive dress and manners of eighteenth-century men of fashion whose gentility had been defined by the magnificence and luxury of clothing and the fineness or delicacy of conversation. Dandyism, by contrast, drew on earlier English qualities—independence, self-command, capriciousness, and a hint of puritanism—to offer a rival style based on meticulous but simple tailoring and imperious, and therefore often impolite, displays of mannered etiquette.
Brummell’s concern for elegance and fashion led to a new way of dressing: a move away from breeches and stockings towards full-length trousers, shirts, starched cravats, waistcoats and long coats. He was known for his snobbishness, competitiveness, elegance, self-confidence and display.

His personality and celebrity caused him to eventually fall out with the Prince of Wales, but he simply moved to 13 Chapel Street in 1812 to establish a new social circle around the duke and duchess of York. Short of money, he turned to gambling, which gave him mixed success. In 1814 he was denounced by fellow members of White’s Club and left England for France on 16 May 1816. He spent the rest of his life in France, continuing his lifestyle despite further financial difficulties.
There have been many television and film adaptations of his life story, including a 1924 film, a 1954 film starring Stewart Granger and Elizabeth Taylor and a 2006 BBC TV movie starring James Purefoy.
