...Elizabeth [Taylor], a shiksa (non-Jewish girl), was studying to convert to Judaism, influenced by Mike Todd's rabbi, Max Nussbaum, who helped her cope with her grief.From: Susan Sackett, The Hollywood Reporter Book of Box Office Hits, Billboard Publications: New York City (1990), page 102:
It is interesting to note that Elizabeth Taylor played a Jewish girl in this film [Ivanhoe (1952)], although she was not raised in this faith. Seven years after Ivanhoe's release, she converted to Judaism. According to Ms. Taylor, in her book Elizabeth Takes Off, "It had absolutely nothing to do with my past marriage to Mike [Todd] or my upcoming marriage to Eddie Fisher, both of whom were Jewish. It was something I had wanted to do for a long time."About the time that Stanley Donen dated actress Elizabeth Taylor, from: Stephen M. Silverman, Dancing on the Ceiling: Stanley Donen and His Movies, Alfred A. Knopf: New York (1996), page 138:
"Elizabeth's mother, Sara, did everything in her power to call it off," Donen said of the romance, which he approximated lated one year. "Her mother hated me in the worst way and did all sorts of nasty things to break us up, including calling Lous B. Mayer, Eddie Mannix, and several other people at the studio." Donen described Sara Taylor as "this very dominating woman, a terrible person. Elizabeth inherited her face and her looks from her father, Francis, but he was a very beaten husband. Sara, I think, at that time certainly was anti-Semitic, despite the fact that Elizabeth subsequently became a Jew."
...In 1957, in anticipation of her third marriage, to the producer Mike Todd (born Avrom Hirsch Goldenbogen), Taylor converted to Judaism.
