Lord Alfred Douglas (1870-1945) third son of the 9th Marquess of Queensberry, is best known for his affair with Oscar Wilde, an affair which led to Wilde's arrest and imprisonment. He was also a writer and translator. Often known by his nickname, 'Bosie', Alfred Douglas was notoriously wild and extravagant.
The Comte de Montesquiou (1855-1921) is perhaps best known as the inspiration for Proust's character the Baron de Charlus. He was a Symbolist poet and a fashionable dandy, an acquaintance of Alphonse Daudet, Edmond de Goncourt, Sarah Bernhardt, and Jean Cocteau.
