1911 Encyclopædia Britannica/Franck
FRANCK. The name of Franck has been given indiscriminately but improperly to painters of the school of Antwerp who belong to the families of Francken (q.v.) and Vrancx (q.v.). One artist truly entitled to be called Franck is Gabriel, who entered the gild of Antwerp in 1605, became its president in 1636 and died in 1639. But his works cannot now be traced.
