In partnership with his brothers Livio (1911–79) and Achille (1918–2002), Milanese industrial designer and architect Pier Giacomo Castiglioni played a role in creating 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. 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.

Vintage Pier Giacomo Achille Castiglioni - Flos 'Arco' Marble & Steel Floor Lamp
By Pier Giacomo Castiglioni, Flos, Achille Castiglioni, Achille & Pier Giacomo Castiglioni
Located in Philadelphia, PA
The Carrera marble base has very slight, barely noticeable yellowing. Telescoping arm shows signs of light oxidation, but operates well. The polished and coated/sealed aluminum shade shows light scuffs and scratches. Wiring is original. Lamp works as it should. In very good shape for being ~70 years old. This lamp is not signed. I'm guessing the manufacturer's sticker label dried out and fell off. Typically, the labels were adhered to the ceramic bulb socket, which would heat up and dry out the glue. Also notice the small hole perforated diffuser, on which the polished aluminum shade rests and pivots, is unusual. Many lamps have the larger holes found on the more recently made examples. The small holes diffuser is found on the vintage Flos Arco...
