SIEFF, REBECCA (1890–1966), first president of *wizo. The eldest daughter of Michael Marks, founder of Marks and Spencer, she was born in Leeds and educated in Manchester. Her husband, Israel *Sieff, and brother, Simon *Marks, were close friends and associates of Chaim *Weizmann, and she was instinctively drawn into their Zionist activity by her strong sense of tradition and historic continuity. She worked with the British Palestine Committee, which prepared the ground for the *Balfour Declaration, and was a founding member and first president of the Federation of Women Zionists of Great Britain and Ireland in 1918. In 1924 she was elected president of wizo, which was founded in July 1920, holding this position until her death. She was especially active in the 1940s as a campaigner against British rule in Palestine and on behalf of Holocaust survivors. Rebecca Sieff was an excellent speaker with a brilliant mind and a forceful personality. She traveled extensively, speaking on behalf of wizo and organizing its branches all over the world. She lived mainly at her home in Tel Mond, Israel, where she is buried.
