In 1978, together with Nikolaus Wyss, Walter Keller founded Der Alltag – Sensationen des Gewöhnlichen; in 1984, with Bice Curiger, Jacqueline Burckhardt and Peter Blum, the art magazine Parkett; in 1991 the photobook publisher Scalo – Books and Looks; and in 1993 he was involved in founding the Fotomuseum Winterthur. An impressive record — yet meagre compared with the overflowing creativity, curiosity, inspiration and energy with which Walter Keller, for almost 40 years, irritated, fascinated and motivated friends, foes, journalists, gallerists, exhibition-makers, photographers, publicists, designers and collectors. On the night of 1 September 2014, Walter Keller died completely unexpectedly. He was a publisher, motivator, editor, coach and networker, but above all an enchanting friend and rousing companion. The book does not seek to explain what he did, but how and why he turned his milieu into exhibits of his own world exhibition. Edited and written by people whose lives he changed and enriched, it is not a chronology but an impressionistic, selective and subjective compendium of his untamed originality.
