Authors who later became famous wrote on the pages of L'Ambrosiano: Carlo Emilio Gadda, who dealt with construction and life in Milan, publishing in the newspaper the prose which he then collected in his Castello di Udine (1934); Alfonso Gatto, who wrote about poetry; Elio Vittorini, who ranged from literature to architecture; Gaetano Afeltra, Riccardo Bacchelli, Camilla Cederna, Ada Negri, Delio Tessa and Salvatore Quasimodo.
