L. Frank Baum was 41 years old when he published his first book. In giving a copy to his sister, he included a personal inscription:
“When I was young I longed to write a great novel that should win me fame. Now that I am getting old my first book is written to amuse children. For aside from my evident inability to do anything ‘great,’ I have learned to regard fame as a will-o-the-wisp which, when caught, is not worth the possession; but to please a child is a sweet and lovely thing that warms one’s heart and brings its own reward.”
The Wonderful Wizard of Oz appeared three years later.
