The American writer and humourist Mark Twain (real name: Samuel Langhorne Clemens, 1835–1910), whose youth novels about Tom Sawyer and Huckleberry Finn made him world famous, travelled around Europe more than once. In his second travel account A Tramp Abroad (1880), he describes among other things his experiences in the Alps. The so-called "music of Switzerland" was in fact the incessant gushing of a mountain stream that kept Twain awake night after night.
