Robert Baden-Powell was a lieutenant-general in the British Army. He is best known for founding the Boy Scouts when he learned that his military textbook Aids to Scouting was being used for training boys in woodcraft. He then wrote Scouting for Boys and retired from the army in 1910 to devote his time to the group. His sister, Agnes, helped to found the Girl Guides and worked with Juliette Gordon Low to bring Girl Scouts to the United States.
