Eliezer David Jaffe (Hebrew: אליעזר דוד יפה; 10 November 1933 – 25 May 2017)[1] was an Israeli professor of social work[2] specializing in philanthropy and non-profit management.
[3] He returned to the USA to complete his education, obtaining degrees in sociology, psychology, and criminology, and a doctorate in social work.
Between 1970 and 1972, at the request of Mayor Teddy Kollek, he headed the Jerusalem Municipal Department of Family and Community Services, introducing major administrative, conceptual and program reforms, all of which have since been adopted nationwide.
Jaffe's research focused on social services to children and families, ethnic stereotypes, and on the nonprofit sector and philanthropy in Israel.
In 2000, Jaffe published a second edition of his book "Giving Wisely: The Israel Guide to Nonprofit and Volunteer Organizations".
He also received the Bernard Revel Memorial Award, presented annually to the most outstanding scholar and community leader among the alumni of Yeshiva University.
