Dr Allan, I want you to meet Pietro Alaria’. There before me stood a short middle-aged man clutching a large book. I was in Italy to make my study. It was explained to me that here was the surveyor who had observed every triangulation station of the Italian network used to drive the Mont Blanc tunnel. Because he had a serious accident, he was unable to complete the task, leaving one triangulation station for another to observe. His and the French surveys were so accurate that the tunnel holed out by 13 cm over a distance of 11.611 km (7.215 miles). Drilling began in 1959 and was completed in 1962. Alaria was typical of the calibre of many surveyors whom I was privileged to meet during my long 20-year FIG journey. Such fellowship was a major, if not the reason for my involvement.
