BIBI-LUPIN, chief of secret police between 1819 and 1830; a former convict. In 1819 he personally arrested at Mme. Vauquer's boarding-house Jacques Collin, alias Vautrin, his old galley-mate and personal enemy. Under the name of Gondureau, Bibi-Lupin had made overtures to Mlle. Michonneau, one of Mme. Vauquer's guests, and through her he had obtained the necessary proofs of the real identity of Vautrin who was then without the pale of the law, but who later, May, 1830, became his successor as chief of secret police.
