Born to Moshe Levy and Masia-Leah (nee Barmack) in the Ukrainian village of Nesolon (then in the Russian Empire). There were only 3-4 Jewish families among the village's 700 or so residents. Jacob's family was quite religious and he was tutored in Jewish studies by private teachers who were brought to the village by his father. He was considered a prodigy and at the early age of 12 he was studying at the Novograd-Volynsky Yeshiva (usually attended by much older students) with the expectation of becoming a rabbi. But the outside world attracted him. Because of the restrictions imposed by the authorities on the admission of Jews into universities, he began external studies that were popular among young Jews who were influenced by the Jewish Enlightenment movement of the 18th-19th century. As a result, he became a Zionist and a socialist, and in 1914, at the age of 20, he left his family and with their support immigrated to Eretz Israel (Ottoman Palestine.^[1]) and turned his back on his religious upbringing.

Upon his arrival in Tel Aviv he enrolled in the Herzliya Hebrew Gymnasium, where he studied for two years (grades X and XI). As a student, he could stay in Eretz Israel without becoming an Ottoman citizen and, even though he spoke Hebrew, he no doubt wanted to absorb the day-to-day spoken Hebrew of the period. It was at that time that he started writing and as a result attracted the attention of his Hebrew literature teacher - the acclaimed writer Y.H. Brenner, who foresaw in him a future as a writer.

When World War I broke out, the Ottoman government changed its policy toward foreign nationals, and especially toward the Jews among them. The Capitulations were canceled and foreign nationals were faced with a choice: obtaining Ottoman citizenship and serve in the Sultan's army or being deported to their home countries. As an ardent Zionist and because of his hatred of the Russian Empire, Jacob had an easy time making a decision, and towards the end of the 1916 school year, immediately after receiving his Turkish citizenship, he was drafted into the Ottoman army and sent, along with many of his class, to officers training in Constantinople (Istanbul).

In 1917 he spent time teaching Hebrew at the Jewish settlement Mesilla Hadasha near Constantinople which was built by the Baron Morris Hirsch as a transit station for the Jewish pioneers from Russia on their way to Eretz Israel, where they received initial training in agriculture. As WWI cut off postal services in Europe, Jacob lost contact with his family, Concerned for their safety, he returned to Ukraine at the end of the war to see his parents. 1919 was a year of many pogroms in Ukraine, in addition to the forced conscription of young men into the Ukrainian Nationalist Army that attempted to keep the country independent of the Soviet Union. Fearing the latter, Jacob spent only a short while with his family and continued to the city of Korets that was then under Polish rule, where he ran a Hebrew school in the summer of 1919. Meir Panas, a student at the school, wrote about the influence that Jacob had:

″Jacob Levy brought with him a fresh essence from the fields and the Galilee. He instilled [in the students] the living Hebrew of Eretz Israel. He brought with him Hebrew terminology for the natural sciences and general studies. To truly appreciate [his] contribution, one needs to remember that there were hardly any Hebrew textbooks for these subjects in Russia at the time.″^[2]

Panas also described Levy’s other activities:

″Jacob, who deeply believed in the kibbutz ideals, was very enthusiastic about the Bolshevik revolution, truly believing that it will make these ideals universally accepted. Therefore, when the Communist party took control of Korets, they appointed him the deputy head of the revolutionary administration. The Bolsheviks so admired his talents and knowledge that he was effectively running it. Because of that respect, the Bolsheviks didn’t close his school down as they did others and Jacob continued as its headmaster.″

In 1920 he was invited to run a school for abandoned children, war orphans in Turkey. His success there, without any prior pedagogical training, determined his future in education, even though he thought of studying engineering. He decided to study education in order to establish a cadre of local Hebrew-Zionist teachers in Turkey and to publish Hebrew textbooks that would meet the needs of Turkish Jewry. For that purpose he traveled to Paris in 1921 to get a degree at the Sorbonne and its affiliated Institute of Psychology & Pedagogy. Unfortunately, while he was studying, the Atatürk revolution took place in Turkey and the new regime did not allow for the establishment of new Hebrew schools.

In 1925, the Jewish Consistory of Bulgaria appointed Jacob the superintendent of the Hebrew schools in Bulgaria.^[3] There Levy devoted himself to teaching and other instructional work in education, organized teachers’ training courses (led by Tzila Greenberg), published textbooks, a Hebrew-Bulgarian dictionary, and reading booklets for children. Together with Ms. Greenberg he published a 3-volume Jewish history textbook titled "Toldot Ameinu" (תולדות עמנו) (The History of Our People). Jacob became active in the "Hashomer Hatzair" youth movement and edited their Hebrew weekly publication "Gilayon", where he also contributed numerous articles and short stories. In those years he started publishing important papers on the teaching of reading and writing in "Hed ha-Hinuch" – the periodical of the teachers’ union in Israel. At the end of his term he returned to Paris to continue his studies and in 1935 received his PhD in educational psychology, a nascent discipline at the time, from the Sorbonne. His thesis – “Maîtres et Eleves” (Teachers & Students) was published by the Sorbonne as a book that year. The book was translated into Italian in 1956 and is being translated into English (2020). In addition to education-related essays published in professional journals such as "Hed Hachinuch" (הד החינוך), he published short stories (under the pseudonym "Aharon Aharoni") in the most important Hebrew periodicals of the period: Y.H. Brenner's "HaAdamah" (האדמה), Joseph Klausner's "HaShiloach" (השילוח) and Jacob Fichman's "Ma-abarot" (מעברות).

Between 1938 and 1956 he was the editor of "Hachinuch" (החינוך) – the Pedagogy and Psychology quarterly of the Israeli Teachers Association and during that time he published many books, including "Israel Ba-Amim" ("Israel Among the Nations") – a series of history textbooks used extensively in Israeli schools, especially in the kibbutz movement. He was an editor of the Encyclopedia Chinuchit" (Educational Encyclopedia אנציקלופדיה חינוכית) and published a series of teacher training books – "Guides" to elementary school grades.^[1]

His children: From his first wife Shoshana Taborovsky-Tavor) a son: Amnon (1918–1995) and from his second wife Shoshana Itygin a son: Avinoam (B. 1945).

Dr. Jacob Levy published numerous books. The most important ones among them: a series of history textbooks (in five volumes) and the translation of four of French-Jewish philosopher Henri Bergson's books into Hebrew.

In writing his history textbooks, Dr. Levy's viewpoint was that studying historical dates is less important that learning the processes that led to historical events. Indeed, in his series "Israel among the nations" one could hardly find dates and history is told in a narrative, compelling way.
