Here's a breakdown:
* Roald Dahl: Published over 17 books for children, including classics like Charlie and the Chocolate Factory, Matilda, and James and the Giant Peach.
* Michael Morpurgo: Known for his children's books, particularly War Horse, which was adapted into a successful film. He has published over 50 books.
While Morpurgo has published a larger number of books, Dahl's works are considered more widely known and influential, making him the more prolific author in terms of impact.
