Achile & Pier Giacomo Castiglioni

Achille and Pier Giacomo Castiglioni were brothers and icons of Italian industrial design who transformed the way we interact with everyday objects from their shared studio in Milan. 

Born into a creative family as the sons of sculptor Giannino Castiglioni, both brothers studied architecture at the Politecnico di Milano before joining forces in a partnership that would define the mid-century aesthetic. Their collaboration was built on a foundation of "playful intelligence," where they reimagined utilitarian items by stripping them down to their essential functions and adding a touch of wit or unexpected material. 

Pier Giacomo Castiglioni (1913–1968) 

Role: Often described as the intellectual engine of the partnership, he was an architect and urban planner. 

Education: Graduated in 1937. 

Academic Work: He was a professor of "Architectonic Composition" at the Politecnico di Milano. 

Recognition: Won five Compasso d'Oro awards during his lifetime. 

Achille Castiglioni (1918–2002) 

Role: The "face" of the duo, known for his curiosity and ability to find inspiration in common gestures and shapes. 

Education: Graduated in 1944. 

Solo Career: After his brother's death, he continued to lead the studio and became a highly influential professor at Turin and Milan. 

Philosophy: He famously told students, "If you are not curious, forget it". 

Awards: He received a record nine Compasso d'Oro awards.
