Germain Sommeiller was a civil engineer from Savoy. He directed the construction of the Fréjus Rail Tunnel between France and Italy, also known as the Mont Cenis Tunnel. This was the first of a series of major tunnels built in the late 19th century to connect northern and southern Europe through the Alps. Sommeiller pioneered the use of pneumatic drilling and dynamite to achieve record-breaking excavation speeds. This 12.8-km tunnel was completed on December 26, 1870, 11 years ahead of schedule. It remained the longest tunnel in the world until the opening of the Gotthard Rail Tunnel in 1882.
