Chaim Walder

As of 2011, the Yeladim Mesaprim al Atzmam series stands at six volumes. Walder has also published two Yeladim Kotvim al Atzmam (Children Write About Themselves) collections and an adult version of Yeladim Mesaprim al Atzmam titled Anashim Mesaprim al Atzmam (Hebrew: אנשים מספרים על עצמם ‎, People Talk About Themselves, translated into English as People Speak), which presents adult-themed stories that have come up on his radio show. Factuality of stories printed is not a given. Asked whether a particular story included in People Speak was true, Walder responded in the negative, stating that "most of it is made up."

In the early 2000s, Walder developed a therapeutic summer camp called Yeladim Mesaprim al Atzmam. At these camps in Bnei Brak, Jerusalem, and Haifa, campers are encouraged to explore new avenues of expression, such as writing and acting out stories.

In 1996, Walder published his first novel for children, Korim Li Tzviki Green! (Hebrew: קוראים לי צביקי גרין ‎, [They] Call Me / My Name is Tzviki Green!, translated into English as That's Me, Tzviki Green!). He named the protagonist after his eldest son Meir Zvi (Zviki), then four years old. As of 2011, he has published 26 volumes of stories and novels for children and adults. More than two million copies of his books are in print.

Walder's first book, Yeladim Mesaprim al Atzmam (Children Talk About Themselves) revolutionized Haredi children's literature by eschewing the "programmatic and religious-indoctrination tone" that had previously characterized books for this age group and introducing the "language of the emotions". The protagonist in each story speaks from the heart about his or her problems and feelings, and the language is "direct and grown-up". The stories are all written in the first person; many are based on true-life incidents that have been told to Walder. Since the publication of the first book in 1993, thousands of children have written letters to Walder, sharing their own feelings and challenges. In 2011, Walder estimated that he had received over 20,000 letters in Hebrew and 10,000 letters in other languages. From these letters, he has learned more about how children think, what interests them, what makes them laugh, and what their fears and worries are. He makes use of the stories that children send him as well as his understanding of a child's mind to craft the plots and dialogue in his tales.

Since 1990, Walder has been a regular columnist for the Yated Ne'eman, writing about social issues. He also hosts a popular radio talk show. He heads the Center for the Child and Family, run by the Bnei Brak municipality, and is a certified educational counselor working with children who have suffered trauma and abuse. In 2003, he received the Magen LeYeled (Defender of the Child) award from the Israel National Council for the Child.

In addition to becoming one of the top five bestselling books of all time in Israel, Yeladim Mesaprim al Atzmam has been translated into eight languages. It paved the way for many new writers to begin publishing "imaginative, thoughtful, emotional, and enjoyable" literature for Haredi children and young adults, a phenomenon that has surged since the late 1990s.

Chaim Walder (born 1969) is an Israeli Haredi rabbi and author of literature for children, adolescents, and adults. In 1993, he became an Israeli publishing sensation with his first book, Yeladim Mesaprim al Atzmam (Hebrew: ילדים מספרים על עצמם ‎, Children Talk About Themselves, translated into English as Kids Speak), which revolutionized literature for Haredi children by introducing young protagonists who speak openly about their problems and feelings. Yeladim Mesaprim al Atzmam became one of the top five bestselling books of all time in Israel, and opened the door for many more writers to produce original fiction for Haredi youth. Walder is also 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.
