Hildebrand Gurlitt
Hildebrand Gurlitt was a German art dealer and art historian who traded in degenerate art during the Nazi era. His collection of 1,406 works was confiscated in 2012 by Bavarian authorities from the apartment of his son, Cornelius Gurlitt.
Gurlitt was born into an artistic family in Dresden in 1895. His father Cornelius Gurlitt was an architect and art historian, his brother Willibald a musicologist, his sister Cornelia a painter and his cousin Wolfgang was an art dealer as well. His grandmother Elisabeth Gurlitt was Jewish, which would prove problematic under Nazi rule he was considered a quarterJew under the Nuremberg laws.
