Early Arco lamp designed by Pier Giacomo & Achille Castiglioni for Flos, 1962

Milanese industrial designer-architects Achille and Pier Giacomo Castiglioni (1918–2002; 1913-68) created some of the most iconic furniture designs in the world, particularly those that originated in the realm of mid-century modern lighting. 

In the late 1930s, after graduating from the acclaimed Polytechnic University of Milan, Pier Giacomo opened a design studio with his brother Livio and likeminded architect Luigi Caccia Dominioni. Achille, also a graduate of Milan Polytechnic, joined the group after completing his studies in 1944. The era’s architects were encountering difficulty in their attempts to secure building commissions, so the group focused on designing practical everyday objects such as the Model 547, a tabletop radio for Phonola that was encased in Bakelite. 

The Castiglioni brothers produced wildly popular and innovative designs throughout the 20th century. While Livio departed the practice in 1952 to pursue lighting design and sound technology on his own, Pier Giacomo and Achille would continue to collaborate on a wealth of projects in the ensuing years. 

Vintage furniture collectors may be familiar with Livio and Italian designer Gianfranco Frattini’s serpent-like Boalum lamp, while Achille’s Taraxacum hanging lamp — created for FLOS with sprayed plastic polymers originally intended for military use — as well as the Arco, Snoopy and Toio lamps, which were the result of the collaboration between Pier Giacomo and Achille, are milestones in modernist lighting design. 

Also for FLOS, Pier Giacomo and Achille created a series of metal frames that, wrapped in the polymer, became floor lamps (Gatto) or pendant lights (Viscontea and Taraxacum), all released in 1960. The Gatto floor lamp takes its name from the Italian word for “cat” and the inspiration for its aesthetic from lighting that George Nelson developed for legendary American furniture manufacturer Howard Miller during the 1940s. Around the same time, the designer Tobia Scarpa (son of the famed Italian architect Carlo Scarpa and one-half of the widely revered postmodern husband-and-wife design duo Afra and Tobia Scarpa) created a floor lamp called Fantasma (1961) using the polymers technique. FLOS continues to make the Castiglionis’ innovative pieces today.

In addition to their provocative lighting works, Pier Giacomo and Achille also created stereo systems, decorative objects, seating, tables and other items for the likes of Brionvega, Alessi, Zanotta, Kartell and more.

Milanese designer and architect Achille Castiglioni sought to inject personality into all of his work, and found deep inspiration in everyday objects. A legend of Italian mid-century modernism, he created iconic, universally loved table lamps, chairs and other lighting and furniture with his likeminded brothers during the postwar years. 

There was the Snoopy lamp, which brings to mind the unmistakable Peanuts character, while the shape of a common street lamp inspired the design behind the Arco floor lamp. Elsewhere, the Toio floor lamp — a provocative fixture in any living room — was made with automotive parts as well as run-of-the-mill recreational gear. 

Castiglioni studied the classics at Liceo Classico Giuseppe Parini, art at the Accademia di Belle Arti di Brera and finally architecture and design at the Polytechnic University of Milan. After graduating in 1944, Castiglioni began working with his brothers Pier Giacomo and Livio at the studio they cofounded with classmate Luigi Caccia Dominioni.

Livio left to pursue lighting design and sound technology, leaving Achille and Pier Giacomo to continue to collaborate on various projects. One such design was the iconic Taraxacum hanging lamp for FLOS which featured a resin “cocoon” created with sprayed plastic polymers that protects its steel core and allows for the diffusion of light.

Castiglioni won Italy’s highest award for industrial design — the Compasso d’Oro — seven times, and the Museum of Modern Art was home to his first individual retrospective in the United States. Castiglioni later taught at the Polytechnic University of Turin and at Polytechnic in Milan.

Castiglioni’s designs remain timeless. Some of them can be found in Tokyo’s Living Design Center Ozone, the Triennale di Milano and the Hangaram Art Museum at the Seoul Arts Center.
