Sergio Mazza was an Italian designer and one of the key figures in the development of Italian lighting design during the postwar period. After studying architecture at the Politecnico di Milano, he began his career working across architecture, interiors, and product design, with a particular focus on lighting. In 1959, together with Ernesto Gismondi, Mazza co-founded Artemide, helping establish the company as one of the leading names in contemporary lighting design. His work was defined by geometric clarity, technical precision, and a careful study of light diffusion, often combining industrial materials with refined formal simplicity. Through both his products and artistic direction, Mazza contributed to shaping a modern approach to lighting in which functionality, atmosphere, and industrial innovation were conceived as an integrated whole.  From 1961, he collaborated with G. Gramigna on the SMc project, working across furniture and industrial design. In 1967, he began designing for Olivari, further expanding his influence on industrial production. His work received numerous distinctions, including a silver medal for Apartamento Italiano at the 10th Triennale di Milano in 1954 and the Compasso d’Oro award for the Delta lamp in 1960. Alongside his design practice, he also co-directed the magazine Ottagono from its foundation until 1988.
