Born into a leading Lithuanian-Jewish rabbinic family, Moshe Aron Reguer initially followed the path of traditional yeshiva education. His adolescence coincided with World War I and its upheavals, pandemics, and pogroms, as well as with new ideas of Haskalah, Zionism, and socialism. His memoir, recently discovered and here translated and published for the first time, discusses his internal struggles and describes the world around him and the people who influenced him. Moshe Aron Reguer wrote his memoir at the age of 23, on the eve of his departure for Eretz Israel in 1926. However, his story did not end there, but continued in British Mandated Palestine and the United States. He kept in touch with the family in Brest-Litovsk until the Nazis destroyed Jewish Lithuania, and some of their correspondence is included within this volume.
