After training at Luca Comerio’s photo studio, at nineteen he opened his own atelier and became a well-known photographer for important figures in Milan. At first, his output ranged from architecture to landscape, but he also immortalized war events in the early century, like the Italian occupation of Tripoli and World War I. Between 1918 and 1920, Aragozzini became interested in industrial and advertising photography for prestigious companies, from FIAT to Pirelli. Afterwards, for the City of Milan he created an important documentation of the new skyscrapers and the subway. After 1950 he began working with his son Fulvio and opened the company “Aragozzini e figli,” continuing his previous collaboration with Italy’s main industries.
