Chaim Eliezer Walder was an Israeli Haredi author of literature for children, adolescents, and adults. In 1993, he became an Israeli publishing sensation with his bestselling first book, Yeladim Mesaprim al Atzmam, which revolutionized literature for Haredi children by introducing young protagonists who speak openly about their problems and feelings, and opened the door for many more writers to produce original fiction for Haredi youth. Walder was a long-time columnist on social issues for the Hebrew daily Yated Ne'eman, an educational counselor, and manager of the Center for the Child and Family, operated by the Bnei Brak municipality.
