The story
Lake Lucerne has formed an important part of Switzerland's transport system for many centuries, and at least since the opening of the first track across the Gotthard Pass in 1230. This trade grew with the opening of a new mail coach road across the pass in 1830. This road had its northern terminus at Flüelen at the extreme eastern end of the lake, and the lake provided the only practical onward link to the cities of northern Switzerland.
In 1835, Casimir Friedrich Knörr decided to take advantage of the growing trade on Lake Lucerne by forming a steamship company and building a paddle steamer, the Stadt Luzern of 1837. His service began operating in 1837, although political pressure by the watermens guilds prevented it operating into the canton of Uri, and hence to Flüelen, for the first year of its operation.
Once this vessel showed the way, various other steamship companies were established. Eventually this led to price cutting, and several steamboat companies failed, or were merged into their rivals. In 1870, the two oldest and largest companies merged to form the Vereinigten Dampfschiffgesellschaft des Vierwaldstättersees (United Steamboat Company of Lake Lucerne). In 1885, this was renamed the Dampfschiffgesellschaft des Vierwaldstättersees (Steamship Company of Lake Lucerne; DGV), and in 1960 it became the SGV.
