Austrian sociologist Otto Neurath was a seminal Modernist figure. Much attention has been given to his achievements in the fields of graphic design and philosophy (Neurath was a member of the Vienna Circle, founder of the Museum of Society and Economy, inventor of the ISOTYPE pictorial system and champion of the Unity of Science movement), yet his involvement with urbanism and architecture has been all but ignored. From 1931 onwards, Neurath collaborated with the International Congress of Modern Architecture and its chief exponents--Cornelis van Eesteren, Sigfried Giedion, Le Corbusier and Laszlo Moholy-Nagy--to develop an international language of urban planning and design. More experimentally, throughout the 1930s a fascination with visual media led to an attempt to franchise the Museum of Society and Economy by establishing international satellite museums. This volume contains a text by curator and writer Nader Vossoughian, which offers a fresh perspective on one of the most versatile intellectuals of the twentieth century.
