The design of Castiglioni Brothers, edited by Dario Scodeller, brings together for the first time the works of the brothers Livio, Pier Giacomo and Achille Castiglioni. The leitmotif of the book is the collaboration between the three architects and designers, whose work marked the history of Italian design: the new contributions by Dario Scodeller, Fiorella Bulegato, Elena Brigi, Daniele Vincenzi, Alberto Bassi and Alessandra Acocella focus on numerous themes, ranging from their first experiments to the creation of innovative projects and objects that have since become icons of design. The pages, filled with archive images, recount the role of Studio Castiglioni in the culture of design, the installations for RAI at the Fiera di Milano, the relationship with business but also with the artistic avant-garde, the importance of “anonymous design” for design practice.
