Barbara Gaffin brought international attention to the desperate circumstances of Ethiopian Jews and helped whole communities flee to Israel. Gaffin began her work by joining a group of North American Jews on a risky mission to Ethiopia. Posing as non-Jewish tourists, they traveled to the closed Jewish villages and documented government violence towards Jews. Gaffin returned to the United States and began giving speeches, writing articles, and lobbying Congress to address the plight of Ethiopian Jews. Her work with the refugees has been ongoing since their relocation to Israel, drawing attention to serious problems in the absorption process and advocating for their rights. She went on to serve in leadership roles for many Jewish organizations, including Friends of Ethiopian Jews, the Jewish Community Relations Council of Boston, the North American Council of Ethiopian, the Dnipro Kehillah Project, and the Zamir Chorale of Boston. She retired in 2020 but is still involved with the boards of many of these groups and others. 

Barbara Gaffin was honored at the 2000 Women Who Dared event in Boston.
