This choral book reconstructs the figure of Héctor Valdés from a diversity of perspectives and materials. The result of meticulous archival work, it delves into the social, political and cultural contexts of which Valdés was a witness and protagonist, specifically the historical moment when the study of classical architecture gave way to enthusiasm for the modern movement. The title addresses various aspects of his life and work: from his prolific production with the firm Bresciani Valdés Castillo Huidobro (BVCH); his commitment as president of the Colegio de Arquitectos of Chile; his public participation as vice president of CORVI; his teaching work, among others.
