following the origin of the boy scouts in 1907 many girls took up scouting. a group of girl scouts were prominent at the crystal palace rally in 1909. after robert baden-powell formed the boy scouts association in 1910 he formed the girl guides and asked his sister agnes to look after the girl guides organisation. a few years later baden-powell's new wife olave st. claire baden-powell (commonly referred to as "lady baden-powell") became involved and, in 1918, was appointed chief guide.
