At the end of
World War I the first large scale orienteering meet was organized in 1918 by Major
Ernst Killander of Stockholm, Sweden. Then President of the Stockholm Amateur Athletic Association,
Killander was a
Scouting Movement leader who saw orienteering as an opportunity to interest youth in athletics. The meet was held south of Stockholm in 1919 and was attended by 220 athletes. Killander is credited with using the
Swedish word
orientering, from which the word orienteering is derived, in publicity materials for this meet.
Killander continued to develop the rules and principles of the sport, and today is widely regarded throughout Scandinavia as the "Father of Orienteering". , first introduced in Sweden in 1933. The sport gained popularity with the development of more reliable compasses in the 1930s. In 1928, Gunnar Tillander, a Swedish orienteer, invented a new style of
bearing compass which allowed the user to quickly take bearings from a map. Tillander took his design to fellow orienteers
Björn, Alvin, and Alvar Kjellström, who were selling basic compasses, and the four men modified Tillander's design and would go on to found
Silva Sweden AB in 1932. In 1933, Silva introduced the
protractor compass. Until the introduction of the
thumb compass, the protractor compass would remain the state of the art in the sport. The first international competition between orienteers of Sweden and Norway was held outside Oslo, Norway, in 1932. By 1934, over a quarter million Swedes were actively participating in the sport, and orienteering had spread to
Finland,
Switzerland, the
Soviet Union and
Hungary. The nations of
Finland,
Norway and
Sweden all established national championships. The Swedish national orienteering society,
Svenska Orienteringsförbundet, the first national orienteering society, was founded in 1936. ==Spread beyond Europe after World War II==
