Mario Ruffini has been committed to studying Luigi Dallapiccola since 1980, year in which he was introduced to him by Carlo Prosperi, Ruffini’s composition teacher. Ruffini’s knowledge of Dallapiccola’s world has thereafter expanded, both on the musical and on the private aspect, thanks to his constant visits to Dallapiccola’s house. This is the training ground where Ruffini, under Laura’s strict guidance, completes his musicological commitment. Thanks to Laura, Ruffini becomes permanent guest conductor at the National Opera Theatre and at the “M.P. Musorgsky” Ballet of St. Petersburg (1990-1995). As a scholar, in 2002 he published L’opera di Luigi Dallapiccola. Catalogo Ragionato (Edizioni Suvini Zerboni), which would be followed by other volumes and over sixty essays on the composer. Again in 2002, he brought the Italian “critofilms” of the Fifties to light, launching the Luigi Dallapiccola Project within the Kunsthistorisches Institut in the Florenz-Max-Planck-Institut. In 2004, he was the scientific secretary of the National Committee for the Celebrations of the 100th anniversary of Luigi Dallapiccola’s birth (1904-2004), and curated the international study conference dedicated to Dallapiccola (Luigi Dallapiccola nel suo secolo) together with Fiamma Nicolodi. For the anniversary, the Italian broadcasting company Rai entrusts him with a series of ten radio broadcasts for the station “Radio Tre Suite”, entitled Vita e opera di Luigi Dallapiccola. In 2016, Ruffini published with the editor Marsilio Luigi Dallapiccola e le Arti figurative; during the presentation of the volume at Palazzo Vecchio, the Luigi Dallapiccola Study Centre was established, with Ruffini appointed as President.
