Sophie Greenspan (1906–90) was national president of the Junior Hadassah of Canada before she moved by herself to Palestine in 1938. In Israel she did secretarial work for David Ben Gurion and Beryl Katzenelson, and she was the first English-language broadcaster for the underground Voice of Israel. Greenspan, her husband, and their two children eventually moved to Los Angeles in 1948, where she worked as a teacher and principal for Jewish day schools. She is also the author of Masada Will Not Fall Again.
