Life would pall if it were all sugar; salt is bitter if taken by itself; but when tasted as part of the dish, it savours the meat. Difficulties are the salt of life. Robert Baden-Powell
Robert Baden-Powell, 1st Baron Baden-Powell, in full Robert Stephenson Smyth Baden-Powell, 1st Baron Baden-Powell of Gilwell, also called (1922–29) Sir Robert Baden-Powell, 1st Baronet, (born February 22, 1857, London, England—died January 8, 1941, Nyeri, Kenya), British army officer who became a national hero for his 217-day defense of Mafeking (now Mafikeng) in the South African War of 1899–1902. He later became famous as founder in 1908 of the Boy Scouts and as cofounder in 1910 of a parallel organization for girls, the Girl Guides. The American Girl Guide organization was founded in 1912 and soon changed its name to the Girl Scouts of the United States of America.
