German painter (b. cca. 1345, Minden, d. 1415, Hamburg).
was a German International Gothic painter primarily of religious art. His most famous surviving work is the large Grabow Altarpiece (or Petri-Altar) in the Kunsthalle Hamburg, the largest and most important North German painting of the period. There is a 45-scene altarpiece of the Apocalypse, probably by his workshop, in the Victoria and Albert Museum in London. He, or his workshop, also produced sculpture, presumably in wood; in fact in his first years in Hamburg most surviving documentation relates to sculpture, including chandeliers. He is first recorded in Hamburg in 1367, and lived there for the rest of his life, becoming a citizen and Master in 1376, and achieving considerable prosperity. In 1390 he made a will in advance of an intended pilgrimage to Rome, but if he made the journey it had no detectable influence on his art. He was married, but his wife had died by his second will in 1410, when he had a surviving daughter. His style is less emotional than that of his Hamburg near-contemporary Master Francke, but has great charm. Bertram was largely forgotten after the Renaissance until the end of the 19th century
