Hadassah, the Women’s Zionist Organization of America (HWZOA) has a lengthy history of activity in the Yishuv and Israel, going back to 1913, about a year after it was founded in New York, and continuing to this day. This activity, outstanding in its scope, continuity, stability, and diversity, encompasses efforts in the sphere of health and medical services and in the welfare of children and youth.

Dutch-born Sarah Bavly was a pioneer nutritionist in the Yishuv who laid the groundwork for Israel's nutritional infrastructure and educational programming, directing Hadassah's hospital nutrition departments and school lunch programs and establishing the State's first College of Nutrition.
