This book is the first comprehensive study dedicated exclusively to the work of Achille Castiglioni, one of the great twentieth-century designers. At work since the 1930s - and still one of the undisputed masters of contemporary design - he has created objects that have become international icons: the Arco, Frisbi and Parentesi lamps, the San Luca armchair, and the Bramante and Leonardo da Vinci tables. His strikingly innovative creations reveal just how much design can reflect an era, defining trends and cultural values. With a rich array of photographs, this book covers the whole range of Castiglioni's work, from architecture to product design, from museum planning to the creation of exhibition spaces.
