Achille Castiglioni was an architect and designer, undisputed protagonist of Italian design since the '50s. He was born in 1918 in Milan, he graduated in architecture and worked on the industrial experimentation with Livio and Pier Giacomo brothers. His genius expresses at its best in the lighting field: his famous lamps such as Arco, Parentesi, and Taccia by Flos or the famous Sanluca armchair, they are true design icons. He demonstrated an extraordinary capability to mix expressivity and functionality through ironic and functional design. He won 9 Compassi d'oro and he became a professor to the architecture faculty in Turin. Moreover, he is the founder of ADI. Many of his works are exhibited at the MoMA in New York and in other prestigious international museums. Alessi, Brionvega, B&B Italia, Flos, Cassina, Kartell and Knoll are just some of the leading companies for which he has worked. He died in Milan in 2002. Since 2011, the Achille Castiglioni Foundation was created so that the Studio Museo in his name would remain open to the public and continue its articulated archive work. For the centenary of his birth, the famous designer Patricia Urquiola, a pupil of the great master, organized a tribute in his memory with the Milan Triennale.
