This publication is dedicated to pioneering curators and presents a unique collection of interviews by Hans Ulrich Obrist : Anne d'Harnoncourt, Werner Hofmann, Jean Leering, Franz Meyer, Seth Siegelaub, Walter Zanini, Johannes Cladders, Lucy Lippard, Walter Hopps, Pontus Hulten, and Harald Szeemann are gathered together in this volume. Their contributions map the evolution of the curatorial field, from early independent curating in the 1960s and 1970s and the experimental institutional programs that developed in Europe and America at this time, through Documenta and the expansion of biennales.
