Nicholas Berggruen

Nicholas Berggruen, the billionaire hedge fund and private equity mogul–and son of the late famed German art dealer Heinz Berggruen– lives in hotel rooms and generally shuns press. He spoke with the Wall Street Journal recently about his recent $2.6 million purchase of a U.K. life insurance company.

No mention of his growing art collection in the story, but in April, the Art Newspaper published reports that Berggruen intends to open a museum in Berlin to house his collection.

In 2000, his father sold his own collection to the Berlin State Museums for $120 million, estimated to be a tenth of its value, forming the Berggruen Museum in Berlin.

Berggruen’s brothers work in the arts. His brother John Berggruen owns a gallery in San Francisco. Another brother, Olivier, is a curator.
