Angelo Mangiarotti was born in Milan on February 26th, 1921, and graduated with a degree in Architecture from the renowned Politecnico di Milano. That same year, he took the opportunity to assist the preparation of the VIII Triennale, effectively introducing him to the vibrant Milanese atmosphere of the design world. He later moved to the United States as a visiting professor at the Illinois Institute of Technology, where he met Frank Lloyd Wright and Walter Gropius, building important relationships for the definition of his personal style.

Back in Italy, in 1955, he embarked on a five-year partnership opening a studio with his colleague and friend Bruno Morassutti. During this period, Mangiarotti took his first steps in the architectural landscape of Milan. From those days comes the famous "Casa a tre cilindri" in the San Siro district, a fine example of architecture perfectly blended with urban planning and the renovation process. The studio expanded on this innovative approach to structural research with the design of an apartment complex in Via Quadronno, and later with the commission of the new Quartiere Feltre, a joint effort with a group of acclaimed Milanese architects.

His architectural vision deeply reflected in these early works: Mangiarotti viewed the discipline as a form of functional art, an artisanal process that had to prioritize functionality and intellectual rigor. This perspective extended to his opinion of industrial design, which he approached with the same care as a craftsman and the precision of an urbanist.
