Athens-born entrepreneur and mega-collector Dimitris Daskalopoulos has been named the winner of the 2014 Leo Award, a prize named after dealer Leo Castelli and given out every other year by Independent Curators International (ICI) to an important figure in the art world, whether it be an artist, curator, collector, patron, dealer, etc. In addition to overseeing the D.Daskalopoulos Collection—works from which have formed the basis of exhibitions at Whitechapel Gallery, the Scottish National Gallery of Modern Art, the Museo Guggenheim Bilbao, and others—Daskalopoulos runs NEON, a contemporary art non-profit in Greece.

In addition to his collection and NEON, Daskalopoulos keeps his fingers in a number of major museums’ pies. He serves on the board of trustees and the collections council of the Guggenheim Foundation, he’s a member the Tate International Council, he’s on the New Museum’s leadership council, and he’s a member of the Museum of Contemporary Art Chicago’s director’s vision council.

He’ll receive the award during ICI’s annual New York City auction and benefit, slated for November 17, 2014. Previous Leo Award winners include Christo and Jeanne-Claude, Miuccia Prada, Dorothy and Roy Lichtenstein, and Dasha Zhukova. Also to be given out at the November gala is ICI’s annual Independent Curatorial Vision Award, whose recipient will be handpicked by the Guggenheim’s Nancy Spector (a shortlist of nominees will be released next month).
