Josef Mengele was a Nazi who kidnapped kids and performed experiments on them (like stitching two twins together in an attempt to create Siamese twins).

Wonka invited kids into his Chocolate Factory and each one had something bad happen to them (Augustus was nearly turned into chocolate, Violet expanded, Veruca nearly got incinerated and Mike was shrunk and stretched).

That's my guess.
