pneumatic rock-drilling machine that, with small modifications, was used in the Mont Cenis Tunnel. On theFebruary 12 ,1853 he conceived how to face the excavation work, being based on the application of the compressed air, and published: "Proposal for the railroad between Susa and Modane of a new system of propulsion with air compressed hydraulic motors (system experimented in England) and first draft of plan for excavation of the Alps".He was disowned while still alive, since the invention was patented by
Germain Sommeiller , but its work was recognized, especially by the architectLuca Beltrami and thanks to the admirers who constructed a monument dedicated to him in Milan, at Largo La Foppa, remembering that: «in February 1853 it was the first one to propose for the tunnel of the Moncenisio original and practical applications of the compressed air becoming meritorious of the arduous enterprise».Bibliography
