A Hungarian psychologist wrote a book on how to raise a genius. He raised three chess grandmasters, two of them became record-breakers and one even became the first female to beat the top ranked male
Laszlo Polgar was a Hungarian psychologist who decided to make his children part of an educational experiment. Polgar believed that "geniuses are made, not born." He argued that children could achieve exceptional things if trained in one subject from an early age.
Polgar and his wife Klara raised three daughters, and decided that their specialist subject would be chess. He trained them in this from when they were very small.
Despite their intense training, the girls seemed to be happy and well adjusted. Chess is a traditionally male-dominated sport and has competitions that are only for women. Polgar did not believe that his daughters had to compete in women-only competitions in order to do well. This belief put them up against the Hungarian Chess Federation at the time.
Polgar's youngest daughter, Judit, was a child prodigy. At age five, she beat a family friend in chess without even looking at the board. She started competing in tournaments at age six. Eventually at age 15, Judit achieved the status of Grandmaster and became the youngest person to do so. Her sisters achieved the status of Grandmaster and International Master as well.
