Moshe David Gaon (Hebrew: משה דוד גאון; 6 September 1889 – 8 October 1958)[1] was a Bosnian Jewish historian, scholar of the Sephardic world, bibliographer, educator, journalist and poet.

Near the end of WWI, he emigrated to Israel, serving one year in the Ottoman army in Beer Sheva, and later studied at the Ezra Teachers' Seminary.

At the outbreak of the War of the Languages, he joined the strikers, and completed his studies at the Seminar Beit Hakerem under the guide of David Yellin.

In 1928, he travelled to Buenos Aires, where he helped edit the "Hebrew Stage" and served as a teacher at the Moroccan Jewish community school in the city.

From his inclination to study the newspapers of the orient, he published many bibliographic articles on the subject in collections on the history of the Palestine press, edited by David Yudelwitz and Zalman Pevsner.
