"We present here the literal transcription of a conversation held with architect Luis Barragán Morfín in November of 1962, in Mexico City, where he himself makes an exposition of his life, studies, experiences and work. - Alejandro Ramírez Ugarte" (HKB Translation) --Page [14]. Conversation between Mexican architect Luis Barragán when Ramírez Ugarte was a young student of architecture. Luis Ramiro Barragán Morfín (b. Guadalajara Mexico 1902-1988), considered the most important Mexican architect, used to be very thrifty in his written production. Through the wise interview conducted by Alejandro Ramírez Ugarte in 1962, Barragán recounts his career, his travels and enunciates some of his main aesthetic and architectural concerns. Hence the crucial importance of this document, published here for the first time. Accompanying in this book are two fundamental and complementary texts: the only lecture that the architect gave in his life, and the enlightening speech given when he received the Pritzker Prize. This trilogy of documents forms a corpus that concerns the heart of the Barraganian vision. A definitive, useful document, open to various readings.
