This publication comprises a unique collection of interviews by Hans Ulrich Obrist mapping the development of the curatorial field--from early independent curators in the 1960s and 70s and the experimental institutional programs developed in Europe and the U.S. through the inception of Documenta and the various biennales and fairs--with pioneering curators Anne D'Harnoncourt, Werner Hoffman, Jean Leering, Franz Meyer, Seth Siegelaub, Walter Zanini, Johannes Cladders, Lucy Lippard, Walter Hopps, Pontus Hulten and Harald Szeemann. Speaking of Szeemann on the occasion of this legendary curator's death in 2005, critic Aaron Schuster summed up, “the image we have of the curator today: the curator-as-artist, a roaming, freelance designer of exhibitions, or in his own witty formulation, a 'spiritual guest worker'... If artists since Marcel Duchamp have affirmed selection and arrangement as legitimate artistic strategies, was it not simply a matter of time before curatorial practice--itself defined by selection and arrangement--would come to be seen as an art that operates on the field of art itself?”
