Winner of the 1990 Pritzker Architecture Prize, Italian architect and theorist Aldo Rossi (1931 1997) gained international renown for his imaginative and starkly beautiful designs. Rossi's writings, drawings and buildings have distinguished him as one of the great architects of our time. They are unique for their simple forms such as cones, cylinders, prisms, and cubes. His work is at once bold yet ordinary, original without being novel, refreshingly simple in appearance but extremely complex in content and meaning. Rossi has been able to follow the lessons of classical architecture without copying them. In a period of diverse styles and influences, Aldo Rossi has eschewed the fashionable and popular to create an architecture singularly all his own. Sketches, drawings, concepts, watercolors, and collages from the early 1960s through to 1998 help us to understand Aldo Rossi the artist and architect, as well as his mindset and how he elaborated his projects. The volume is complete with a register of the Aldo Rossi Foundation's works. This is truly a valuable tool for scholars.
