What is the story of Willy Wonka?

"The whimsical, wacky, and wondrous character of Willy Wonka made his first appearance in Roald Dahl's 1964 children's novel "Charlie and the Chocolate Factory." When the fictional factory owner opened up the doors of his company, readers were welcomed into his world of pure imagination . . . and chocolate! Wonka went on to dazzle a whole new set of fans in the 1971 film that brought Dahl's characters to life. Since then, there have been other movie adaptations, books, musicals, and even theme park rides that bring the world just a little bit closer to this fantastic chocolatier"--Provided by publisher.
