The Italian architect and designer brothers Achille Castiglioni (1918-2002) and Pier Giacomo Castiglioni (1913-1968) are among the greatest names of modern Italian design. Their father was the notable Italian architect Giannino Castiglioni, and also their brother Livio Castiglioni became an architect and designer. Achille and Pier Giacomo both studied architecture at the Politecnico di Milano and later worked there as teachers. Their collaboration was productive and innovative, and the designs were often radical and humorous. Some of their best-known works include the Mezzadro chair featuring a tractor seat, and many lighting designs for Flos, including the Snoopy table lamp and the floor lamp Toio that is lit by a car headlight. Pier Giacomo, who passed away in 1968, won six Compasso d’Oro awards during his career, and Achille was awarded the prestigious design award nine times.
