A chamberlain (Latin: camerarius) is an officer in charge of managing a household. In many countries there are ceremonial posts associated with the household of the sovereign.
Historically, many institutions and governments – monasteries, cathedrals and cities – also had the post of chamberlain, who usually had charge of finances. The Finance Director of the City of London is still called the Chamberlain, while New York City had such a chamberlain, who managed city accounts, until the early 20th century.
From the Old French chamberlain, chamberlenc, Modern French chambellan, from Old High German Chamarling, Chamarlinc, whence also the Medieval Latin cambellanus, camerlingus, camerlengus; Italian camerlingo; Spanish camerlengo, compounded of Old High German Chamara, Kamara [Latin camera, “chamber”], and the German suffix -ling.
