We thank our friend Sheila Hicks for her assistance in editing of the text. Book design: Massimo Vignelli with Beatriz Cifuentes This book is affectionately dedicated to Lella, my wife and professional partner. Together we shared our intellectual experiences and growing process from the very beginning of our professional lives. Her creative intuition and sharp criticism have enriched my life and have been the structural strength of our collaboration, without which my work would have been worth much less. 4
