Lake Neuchâtel
Suchard was not only a chocolatier but also had interest in other areas. In 1834 he introduced and captained the first steamer, "Industriel", on Lake Neuchâtel. His interest in managing river water and controlling floods led to the sinking of the water level in Lake Neuchâtel. The lowered lake shoreline revealed the Celtic settlement of La Tène dating back to around 450 BC.
