Tens of thousands of Jewish children were orphaned during World War I and in the subsequent years of conflict. In response, Jewish leaders in Poland established CENTOS, the Central Union of Associations for Jewish Orphan Care. Through CENTOS, social workers and other professionals cooperated to offer Jewish children the preparation necessary to survive during a turbulent period. They established new organizations that functioned beyond the authority of the recognized Jewish community and with the support of Polish officials. The work of CENTOS exemplifies the community's goal to build a Jewish future. Translations of sources from CENTOS publications in Yiddish and Polish describe the lives of the orphaned Jewish children and the tireless efforts of adults to better the children's circumstances.
