History
Bouldering's documented origins may be found in the United Kingdom, France, and Italy in the last quarter of the 19th century [2]. The British coined the word bouldering at that time. For many years, bouldering was usually viewed as training for climbers, although, in the 1930s and late 1940s, Pierre Allain and his companions enjoyed bouldering for its own sake in Fontainebleau, considered by many to be the Mecca of bouldering. The first climber to actually make bouldering his primary specialty (in the mid 1950s) and to advocate its acceptance as a legitimate sport not restricted to a particular area was John Gill, an amateur gymnast who found the challenge and movement of bouldering enjoyable.
