More than 1,400 works were found in Cornelius Gurlitt’s Munich apartment, including pieces by Picasso and Matisse.
Many of the artworks were feared lost or destroyed before tax investigators uncovered his priceless collection in 2012.
Cornelius Gurlitt was the son of Adolf Hitler’s art dealer, Hildebrand Gurlitt.
Hildebrand Gurlitt was ordered to deal in works that had been seized from Jews, or which the Nazis considered “degenerate” and had removed from German museums.
Cornelius Gurlitt, whose death followed ill-health after heart surgery, told Der Spiegel magazine last November that he would never willingly give up the paintings.
“I haven’t loved anything more than my pictures in my life,” he said.
But he changed his position, agreeing to co-operate with the German authorities on establishing the paintings’ provenance, and returning them if they were shown to be stolen.
German Culture Minister Monika Gruetters praised him for that, saying: “He will be rightly recognized and respected for taking this step.”
Cornelius Gurlitt died “in his apartment in Schwabing, in the presence of a doctor,” spokesman Stephan Holzinger said in a statement.
He did not live an extravagant life but would sell a painting only when he needed money.
Cornelius Gurlitt’s collection only came to light after a routine check found he was carrying wads of cash on a train from Switzerland, triggering a tax inquiry.
Investigators found more than 1,400 works in his flat in Munich in February 2012 – though they only revealed the discovery in late 2013 – and a further 60 in his house near Salzburg, Austria, earlier this year.
Among them were works by Pierre-Auguste Renoir, Marc Chagall, Emil Nolde and Max Liebermann.
The collection is estimated to be worth up to a billion euros ($1.35 billion).
Under German law, Cornelius Gurlitt was not compelled to return any paintings to their owners, as he was protected by a statute of limitations, which negates any claim for incidents that happened more than 30 years ago.
