This book, a reflection on Herman Hertzberger’s legacy, spanning from 1959 to today, is as much about making architecture as it is about world-making. The Dutch architect never considered his works as stand-alone objects, but rather as parts of webs of connections on different scales. In this collection of texts, photographs, drawings, his own work, and architecture and art by others, all of these layers come together to form a universe of inspirations, ideas, and solutions – in Hertzberger’s words, his ‘musée imaginaire’. Edited by Suzanne Mulder and Hans Ibelings, the book is written and compiled by Hertzberger himself and features an essay by Thomas Hertzberger.
