István Csók (February 13, 1865, Sáregres – February 1, 1961) was a HungarianImpressionist painter. Csok lived and exhibited in Paris for a portion of his life. He became most famous in Hungary for his nudes, portraits, and landscapes of the Lake Balaton. Csok had many international exhibitions in such cities as Rome, San Francisco, Pittsburgh, and London. He won the Kossuth Prize twice.
Though rarely seen in the West nowadays, an example of Csók's work can be glimpsed behind the opening credits of the 1971 film Countess Dracula. This is an 1896 painting showing serial murderess Countess Elizabeth Bathory enjoying the torture of some young women: in an inner courtyard of one of her castles, naked girls are being drenched with water and allowed to freeze to death in the snow. The original painting was destroyed in World War II.
