Roald Dahl is famous as one of the greatest storytellers for children of the 20th century. He is a British author renowned for his popular children's books and short stories, which often feature imaginative, darkly comic, and unsentimental themes. His books have sold more than 300 million copies worldwide and have been translated into 63 languages. Some of his most famous works include "Charlie and the Chocolate Factory," "Matilda," "The BFG," "James and the Giant Peach," "The Witches," and "Fantastic Mr. Fox." His stories are known for unpredictable plots, creative language, and memorable characters, with villains often being wicked adults opposed by kind-hearted children. Many of his works have been adapted into popular films and stage shows. In addition to children's literature, Dahl wrote short stories for adults, screenplays (including for the James Bond film "You Only Live Twice"), and poetry. His narrative style rewards creativity and playfulness over obedience, making his books enduring favorites across generations. Dahl's influence and popularity remain strong, celebrated yearly on Roald Dahl Day (September 13).
