Marie Joseph Robert Anatole, Comte de Montesquiou-Fézensac, was a French aesthete, Symbolist poet, art collector and dandy. He is reputed to have been the inspiration both for Jean des Esseintes in Joris-Karl Huysmans' À rebours and, most famously, for the Baron de Charlus in Marcel Proust's À la recherche du temps perdu. He also won a bronze medal in the hacks and hunter combined event at the 1900 Summer Olympics.
