Pier Giacomo Castiglioni—nicknamed Popo—was a prominent Italian architect and a pioneer of Italian design. According to Dino Gavina, he was one of the ten best designers in the world.

The son of Giannino Castiglioni, a renowned Milanese sculptor, he graduated in architecture in 1937 from the Politecnico University of Milan, for which he designed the official signet in 1944.

In 1938 he established the famous Studio Castiglioni in Milan with his elder brother Livio (1911-1979) and also started working with Luigi Caccia Dominioni—another leading Italian architect and designer—with whom he collaborated until 1945.

In 1944 his younger brother Achille joined him and Livio at Studio Castiglioni and they officially worked all together until 1953, when Livio left the trio. However, Pier Giacomo and Achille continued collaborating during his entire life.

They also involved in their work many other prominent Italian designers including Anna Castelli Ferrieri, Bruno Munari, Enzo Mari, Erberto Carboni, Fulvio Bianconi, Giancarlo Iliprandi, Grazia Varisco, Heinz Waibl, Italo Lupi—who was Pier Giacomo’s teaching assistant at the Politecnico University—, Max Huber, Michele Provinciali, Pino Tovaglia, and others.

During his career, he worked on the whole field of design from architecture to exhibition design, on to furniture, product, and light design. He served many renowned Italian design companies including Alessi, Brionvega, Cassina, Flos, Gavina, and Zanotta as well as many major corporations such as ENI, Montecatini, Pirelli, and RAI.

In 1938 he started teaching at the Politecnico University of Milan, holding this appointment for his whole life. In 1954 he cofounded the Movimento Studi Architettura (Architectural Study Movement), while in 1956 he was a founding member of ADI—Associazione Disegno Industriale (Industrial Design Association), the first Italian design association for which he acted as a jury member of the Compasso d’Oro contest.

Many of the pieces he designed are now part of the collection of major museums such as the MoMA in New York and the RIBA (Royal Institute of British Architects) in London. He also received numerous recognitions including five Compasso d’Oro awards (1955-1967), one Triennale Bronze Medal (1947), two Silver Medals (1957, 1960), two Gold Medals (1957, 1960), and two Triennale Grand Prix (1951, 1954).

He died in Milan in 1968.

Quotations
 “Any shape is expressed in function of something. Any meaning that could be communicated through a shape can be identified as a function. So the choice of functions is the first act of design and it binds the creative process until the end”, 1965.

 “One of the key features of the design process is the logical commitment that links the formal expression to the content choices made by the designer”, 1965.

 “Pier Giacomo was an extraordinary gentleman of great elegance and sharp intelligence. A man of few words, who always showed extraordinary precision and determination,” Italo Lupi (Autobiografia Grafica, 2013).

 “The designer shouldn’t be seduced by a nice looking shape. He has to analyze and study the functions, the material, the needs of mass production, the prices. And until he has not acquired the knowledge of these aspects he should not be satisfied of his work”, 1953.

 “The judging criteria towards an object are always conditioned by the assessment—known or intuitable—of the situations from which the object comes and that the object will affect”, 1965.

 “The media more often talk about Achille than Pier Giacomo. But they are unaware that Popo (Pier Giacomo) was the fundamental reference of Cici (Achille). Pier Giacomo was the one who gave authority to their ideas,” Massimo Vignelli.

 “Thirty years after his death, Milan has not yet realized that one of his best sons, Pier Giacomo Castiglioni, has been the greatest master of Italian industrial design,” Dino Gavina, 1998.

Designed with Achille Castiglioni.

Lounge Chair (Gavina, Knoll, Bernini, Poltrona Frau)
