Roald who wrote "Matilda"

DAHL

This Norwegian-British author also penned "Charlie and the Chocolate Factory" and served as a fighter pilot in World War II.

This clue asks for the first name of the famous children’s author who wrote Matilda. Roald Dahl is well-known for classic books like Charlie and the Chocolate Factory and James and the Giant Peach, so his last name might come to mind first—but the clue specifically wants his first name. The answer is "DAHL," but since the clue asks for "Roald," you’d actually write "DAHL" in the grid if the puzzle is designed that way (sometimes crosswords use last names even when first names are clued). Double-check the letter count to confirm it fits.
