Joseph Eidelberg (Hebrew: יוסף אידלברג) (February 8, 1916 – August 21, 1985) was an Israeli military commander and a plant manager of large Israeli corporations. During his career he developed a hobby of exploring religions’ roots and languages. He became a linguistics researcher, a scholar speaking seven languages, an Historian explorer, and an author of three books. His research work focused on the two most puzzling mysteries in Jewish history: The Exodus, a 40-year desert travel of the Israelites from Egypt to Canaan, and the Ten Lost Tribes of Israel, which were never found. His research claimed to show evidence that the Exodus journey took place in North Africa including Nigeria, the land of Igbo Jews, and to have found evidence supporting the Japanese-Jewish common ancestry theory. Publications of work by Eidelberg, from 1972 to 2015, amount to “15 works, in 35 publications, in 3 languages and 153 library holdings”.
