Where is the Collection of Books from the DDR?

A brief bleg for my intelligent, good-looking readers. A few months ago, I was leafing through a newspaper and saw an article about someone who had started a collection of books published in East Germany. The person had rented a big warehouse and already collected something like 200,000 books. I believe this person was some sort of entertainer who had some kind of link to the DDR. The plan is to create a big library of East German books, to preserve some of the cultural memory of East Germany.

Can anyone help me with the name of this person and of the project? Thanks in advance!
