On that day we think about our sister Guides all over the world.Robert Baden-Powell was born on February 22, 1857, in England. He wrote a book called "Scouting for Boys," and later founded the Boy Scouts and Girl Guides. Lord Baden-Powell asked his sister Agnes Baden-Powell to take charge of Girl Guides.In 1912 Lord Baden-Powell married Olave St. Claire Soames. She became involved in the Girl Guide movement and later became the World Chief Guide. After her husband's death in 1941, Lady Baden-Powell continued to promote Guiding and Scouting.
