She personally taught her own children and exposed them to new ideas and inventions. She gave lessons to her younger son, Louis, until he was ten years of age. He said of her in 1968 that she was "a walking encyclopedia. All through her life she stored up knowledge on all sorts of subjects, and she had the great gift of being able to make it all interesting when she taught it to me. She was completely methodical; we had time-tables for each subject, and I had to do preparation, and so forth. She taught me to enjoy working hard, and to be thorough. She was outspoken and open-minded to a degree quite unusual in members of the Royal Family. And she was also entirely free from prejudice about politics or colour and things of that kind."
