Caspar Badrutt some Englishmen adapted a type of delivery sled for daring dashes down twisting narrow streets of St. Moritz. Subsequently, other tourists wanted a Victorian ride, and larger steerable devices were contrived: the early luge/skeleton individual sleds, and the bobsleigh (or bobsled). Careening around the town's streets became increasingly popular, but the incidence and frequency of pedestrian collisions and risk to life grew proportionately. Therefore, Badrutt stepped in and created the first purpose-built half-pipe track, now familiar from the Winter Olympic Games. This track later became the model for the Cresta Run skeleton racing track, built in 1884. Caspar Badrutt Swiss
