Overview
Agnes Smyth Baden-Powell (16 December 1858 – 2 June 1945) was the younger sister of Robert Baden-Powell, 1st Baron Baden-Powell, and was most noted for her work in establishing the Girl Guide movement as a female counterpart to her older brother's Scouting Movement.
Early life
Agnes was the thirteenth of fourteen children of her father, the Reverend Baden Powell, who had married twice previously. He was the Savilian Professor of Geometry at the University of Oxford from 1827 to 1860. She was his third daughter, but the elder two had died before Agnes was born; she was her mother's only daughter.
Her mother, the third wife of Baden Powell (the previous two having died) was a gifted musician and artist, Henrietta Grace Smyth, the elder daughter of Admiral William Henry Smyth and his wife Annarella.
Apart from Robert already mentioned above, among Agnes's brothers were Warington Baden-Powell, Sir George Baden-Powell, Frank Baden-Powell, and Baden Baden-Powell.
