The monograph Robert & Trix Haussmann launches the publication series STUDIOLO / Edition Patrick Frey, a collaboration between the publisher and the exhibition space STUDIOLO. Curators Fredi Fischli and Niels Olsen run a diverse program of contemporary art production in a studio house in Zurich. The exhibition The Log-O-Rhythmic Slide Rule in spring 2012 focused on the work of Trix and Robert Haussmann and serves as the starting point for this publication, which offers in-depth insights into the rich oeuvre of the Swiss architect-designer duo through images, essays, artist contributions, and a conversation. Trix and Robert Haussmann are among the most important architects, designers, and theorists shaping and redefining classical modernism in Switzerland. Their life's work currently includes around 650 realized projects; in Zurich, among others, the Da-Capo-Bar.
