[11][13] He also helped establish and was an important member of local organizations, such as the Club de la Unión or the Peruvian chapter of Pro Ticino, a diaspora organization for Ticinese Swiss in Peru, becoming an important member of the diaspora.

A building named after him[11] was built in the site in the 1920s, originally houseing Marcionelli's mining company's offices.
