“Harald Szeemann, an influential Swiss museum curator whose groundbreaking exhibitions helped redefine his profession, died last Friday in the Ticino region of Switzerland. He was 71. His death was announced by the Venice Biennale and the Kunsthaus Zürich, for which he worked. Mr. Szeemann was often said to be the first independent, or freelance, curator. He invented the curator as art star, a globe-trotting, deal-making, usually male impresario of large-scale exhibitions that bore the imprint of a single vision and succeeded or failed on the strength of site-specific works executed specially for the show.”
