Born in Oleggio (Novara) in 1927, Carlo Mazzeri graduated in architecture from the Istituto Universitario di Architettura in Venice in 1956 and, after an early collaboration with Carlo Scarpa in Venice, with the architect Mario Righini’s studio he took part in the competition for the Colonia Olivetti in Brusson and the Carrara Chamber of Commerce, and took one of the top places. In 1957 he designed the cocktail shaker “870” with Luigi Massoni, which was one of the first Alessi objects designed by external collaborators and which is still in production and can be found in bars worldwide. In the ‘60s and ‘70s with Anselmo Vitale he designed a complete collection of objects for Alessi which were primarily for use in the hotel industry. He was involved in civil and industrial construction, responsible among other things for the Alessi plant in Omegna (1960-1971), the Girmi electrical household appliances factory (1962) and the Lagostina offices (1964), which were also in Omegna, the renovation of the driers and the new warehouse for 3M Italia in Ferrania (1970) and the Salumificio Romano Mainelli in Oleggio (1972). In the field of industrial design he has also collaborated with Girmi, Lagostina, Bialetti, Indesit, Fonderie Filiberti and Triplex. In 1973 he opened a studio of architecture in Novara, becoming involved in civil architecture, restoration and town planning.
