László Polgár (born 11 May 1946 in Gyöngyös), is a Hungarian chess teacher and educational psychologist.
He is the father of the famous Polgár sisters: Zsuzsa, Zsófia, and Judit, whom he raised to be chess prodigies, with Judit and Zsuzsa becoming the best and second best female chess players in the world, respectively.
Judit is widely considered to be the greatest female chess player ever as she is the only woman to have been ranked in the top 10 worldwide, while Susan became the Women's World Chess Champion.
He has written well-known chess books such as Chess: 5334 Problems, Combinations, and Games and Reform Chess, a survey of chess variants.
He is also considered a pioneer theorist in child-rearing, who believes "geniuses are made, not born".
Polgár's experiment with his daughters has been called "one of the most amazing experiments…in the history of human education." He has been "portrayed by his detractors as a Dr.
Frankenstein" and viewed by his admirers as "a Houdini", noted Peter Maas in the Washington Post in 1992.
