Mary Elizabeth Kramer was born on August 6, 1948, in
Cleveland, Ohio, United States. From 1965 to 1969, she was educated at
Swarthmore College in Pennsylvania,
majoring in mathematics, philosophy and history, and graduating
summa cum laude in 1969. She then attended
Harvard University as a mathematics graduate student: she completed her
Master of Arts (MA) degree in 1971 and her
Doctor of Philosophy (PhD) degree in 1972. They both gradually felt more and more drawn to
Orthodox Judaism and considered themselves
Haredi by the time they had completed their doctorates. The couple made
aliyah (moved to Israel) in 1972. Together, she and her husband had two children: this was a small family by Haredi standards, and they raised four more
foster children. They live in
Bnei Brak, a Haredi city near Tel Aviv. ==Career==
