A collection is like a dinner party. It is made up of the people you invite, but also the people you don't.

Geographically speaking, I was born on a French island - the île d'Oléron. Otherwise, I come from a milieu where culture was of the utmost importance. I learned music even before I learned to read. I always read books beyond my years.

There's nothing that really motivates me anymore and demands that I get up in the morning. In the past it was Yves Saint Laurent.

On my own account I certainly wouldn't have become the director of a couture house. I didn't have sufficient admiration for fashion as such to have done so.

There was an exchange between me and Andy Warhol. We met, we liked each other, we appreciated each other. He would come to us for Easter in Marrakech. In September we would meet up in Venice. And every time I went to New York I would spend some time with him at the Factory, where we would have dinner together. He's a man that I admired deeply. He shook up the notion of painting - not as much as Marcel Duchamp had done, but he was part of the same general movement. And then we both admired art deco.

In April 2007 I learned that Yves Saint Laurent had a brain tumor, and he died on June 1, 2008. During those 14 months I had plenty of time to think about what would happen. There was only one solution: the auction. An auction establishes memory. That's what I want to do.

I never abandoned Yves Saint Laurent. I used to have lunch with him twice a week. I also saw him every Saturday. My presence beside him was even more important in his bad times. But that didn't leave me a great deal of room in which to maneuver. Freedom is an intellectual space. But I don't use it.
