Tourism begins with British mountaineers climbing the main peaks of the Bernese Alps in the early 19th century (Jungfrau 1811, Finsteraarhorn 1812). The Alpine Club in London was founded in 1857. Reconvalescence in the Alpine climate, in particular from Tuberculosis, is another important branch of tourism in the 19th and early 20th centuries for example in Davos, Graubünden. Due to the prominence of the Bernese Alps in British mountaineering, the Bernese Oberland was long especially known as a tourist destination. Meiringen's Reichenbach Falls achieved literary fame as it was the site of the fictional death of Sir Arthur Conan Doyle's Sherlock Holmes (1893). The first organised tourist holidays to Switzerland were offered during the 19th century by the Thomas Cook and Lunn Travel companies.
