Master Bertram von Minden was a German painter working in Hamburg from 1367 to c.1415. The most important picture attributed to him is the Grabow Altar (c.1379/83, Hamburg, Kunsthalle). Others are in Hanover, Paris (Musée des Arts Décoratifs) and London (Victoria and Albert Museum). He was a precursor of the realistic Flemish approach of the 15th century, and also of the 'soft style', and he may have had some contact with Theodoric of Prague and with French art. //
