Short answers, pulled from the story.
Roald Dahl wrote Charlie and the Chocolate Factory in 1964 while sitting at his desk. The story idea originated from his time as a student at Repton School in Derbyshire during the 1920s.
The concept came from Dahl's experience with Cadbury chocolate companies sending test packages to schoolchildren for feedback on new products. He found espionage between England's two largest chocolate makers, Cadbury and Rowntree's, fascinating and used it to create the character Slugworth.
Dahl published a revised edition where Oompa-Loompas looked white and resembled hippies instead of African pygmies after concerns from the NAACP. In 2023 publisher Puffin made over eighty additional changes to remove offensive language including descriptions of them living in trees or wearing deerskin.
