Léon Alfred Fourneau was a French humourist, music-hall artist, playwright and songwriter. Originally trained as a lawyer he invented the stage- and penname Xanrof by inversion of the Latin fornax of his French surname fourneau ("furnace"), before finally legally changing his name to Léon Xanrof. Yvette Guilbert experienced early success singing Xanrof's songs at Rodolphe Salis' cabaret Le Chat Noir.
