Cornelius Gurlitt is a reclusive man, but he was recently found to be holding one of the world’s biggest private art collections – close to 1,500 pieces that he had stored at his homes in Munich and Salzburg.
It is though much of it came from his father, a dealer licensed by the Nazis to buy and sell art, and may have been stolen from Jewish families.
The BBC’s Stephen Evans was granted exclusive access to look at some of the long-lost masterpieces which had been kept hidden for decades.
