In 2005, the German Restitution Commission recommended that the German Federal Government restitute three paintings by Blechen to the heirs of Julius and Clara Freund, who were persecuted as Jews by the Nazi regime, and had fled to England in 1939. In 2008, the Blechen "
Scene of a forest with a castle, on the water front " was identified in a
Sotheby's auction catalogue by the family of
Alfred Sommerguth, a German Jewish art collector persecuted by the Nazis. Sommerguth had "fled to Cuba in 1941 at the age of 82, before reaching New York where he died a destitute in 1950". The painting was removed from the sale and returned to the heirs. In 2012 the Blechen, “Hoehenzug mit blauen Schatten” (Mountain Range With Blue Shadows), was restituted to the heirs of Martha Liebermann, who took poison at the age of 85 to escape deportation to a Nazi concentration camp. Seized by the Nazis and intended for Adolf Hitler's planned “Fuehrermuseum, they were handed to the German government by the Allies after World War II on the understanding that they would be returned to the original owner. In 2014 the Staatliche Kunstsammlung Karlsruhe discovered the Nazi-era history of Blechen’s
Santa Scholastica and restituted the artwork to the heirs of the Jewish publisher and art collector
Rudolf Mosse. In 2016, however, the Austrian Art Restitution Advisory Board decided against restituting three works by Blechen in the
Albertina. They had belonged to
Julius Freund. ==Gallery==
