Pier Giacomo Castiglioni (1913-1968) and Achille (1918-2002) are the eldest and the youngest of the three Castiglioni brothers who all studied architecture at the Milan Polytechnic. The two Castiglioni brothers were interested in both technology and art and in the 1940s began their original professional partnership, "Castiglioni brothers". The company was especially successful with their lamps for Arredoluce, Flos, and Artemide. The brothers worked from the viewpoint that design must restructure an object's function, form and production process, a philosophy they applied to every work they produced. Published in the same style as the successful 'Minimum Architects' series, the 'Minimum Design' series includes books about the major figures in the field of design, creators of objects that have become a part of our daily lives. The lamp on our desk, the chair we are sitting on or the glasses we are wearing have a genius behind to be discovered. These volumes will introduce in a practical manner the personalities and the works of the world's major designers by way of an historical-critical introduction to the work and life of each individual designer.An accurate selection of the designer's most famous objects arranged in chronological order and a critique of his or her work summarising the most significant reviews published in magazines and newspapers will complete the subject.
