Katherine Kath (born Rose Marie Lily Faess; 11 August 1920 – 17 November 2012) was a French prima ballerina at the Theatre du Chatelet in Paris, who became an actress after suffering from an injury which destroyed her chances of continuing her career. Kath was born in Berck, Pas-de-Calais, France, where she also died, at age 92 in 2012, from undisclosed causes. She appeared in many international films and television programmes during her acting career. She met British filmmaker Jack Clayton in 1952, during the making of Moulin Rouge, in which she portrayed the can-can dancer La Goulue and on which Clayton was the assistant director. The couple married in 1953, following Clayton's divorce from his first wife, Christine Norden, but the union was shortlived.
