William-Adolphe Bouguereau
Sources on his full name are contradictory: it is sometimes given as "William-Adolphe Bouguereau" (composed name), "William Adolphe Bouguereau" (usual and civil-only names according to the French tradition), while in other occasions it appears as "Adolphe William Bouguereau" (with Adolphe as the usual name). However, he used to sign his works simply as William Bouguereau (hinting "William" was his given name, whatever the order), or more precisely as "W.Bouguereau.date" (French alphabet) and later as "W-BOVGVEREAV-date" (Latin alphabet).
