Italian-Argentine violin maker Camillo Mandelli was born in 1873 in the Lombardy region of Calco, Italy, and died in Sesto San Giovanni in Milan in 1956. He studied violin making in Milan with the Antoniazzi brothers and Giuseppe Leandro Bisiach (Leandro Sr.), founders of the modern Milanese school and leaders of the renaissance of Cremonese violin making in Italy in the late 19th and early 20th centuries. In 1889, Mandelli emigrated to Buenos Aires, Argentina, where, known as "Camillo da Calco" (also "di Calco"), he worked for several years, before returning to Milan in 1936. Considered one of the most important modern Italian makers of the early 20th century, many of Mandelli's instruments are housed in the collection of the Isaac Fernández Blanco Museum of Spanish-American Art in Buenos Aires. His instruments are highly desirable among professional players.
