This portrait of a young man, who was twenty-four in 1543 (and therefore born circa 1519), was looted from the Danzig Museum (now the Gdańsk National Museum) by the German occupation forces in 1943, then claimed by the Soviet Union’s Red Army as spoils of war in 1945. The sitter was formerly thought to be a merchant of the Steelyard (Stalhof) in London. In 1913 Georg Habich identified the sitter as Heinrich von Schwarzwald, but Heinrich’s birth date of 8 July 1517 rules him out as the sitter, and in any case his merchant’s mark does not correspond to the "Z or very widely placed N" on the sitter's signet ring. A different claim was made at the same time by Hans Secker, who said that by tradition, the sitter was known as Johann von Schwarzwaldt, but if this was Heinrich’s son, he too can be ruled out. The portrait, one of a number of works of art subject to restitution requests by the Polish government, is located at the Pushkin State Museum of Fine Arts, Moscow. An earlier portrait of the same individual is located in the Royal Collections, The Hague: MI-492 where he is identified as Hans Schwarzwaldt (1513-1575). In 2016 the young man was identified as Gregory Cromwell (c.1520–1551), son of Thomas Cromwell, Earl of Essex, chief minister to Henry VIII.
