Petr Ginz
This made Ginz half-Jewish. Ginz showed signs of high intelligence, before the age of 8. He wrote his first novel when he was 8 years old. He wrote four more novels, after that. The last novel was written and completed when he was 14, shortly before his transportation to the Theresienstadt Ghetto. The novels were mostly written in the style of Jules Verne, and were even illustrated with his own paintings. Ginz spoke two languages fluently from early childhood. His parents were very interested in studying and learning Esperanto, and thus this became Ginz' second native language, apart from Czech.
