Architect and designer The younger brother of the designers Luigi and Pier Giacomo Castiglioni, Achille Castiglioni set up a design practice with Pier Giacomo in 1945. They played an important role in the postwar Italian design movement, working primarily on exhibition and product design. Together, they created the ‘Turbino’ desk lamp, produced by Arredoluce in 1949, the ‘Spalter’ vacuum cleaner produced by Rem in 1956, and the ‘Arco’ lamp produced in 1962. Following his brother’s death in 1968, Achille went on to work on oil and vinegar flasks for Alessi (1980) and the ‘Gibigiana’ light for Flos in 1980. He remains one of Italy’s leading designers and continues to work in Milan in a modest studio.
