Abraham Shalom Yahuda (Hebrew: אברהם שלום יהודה; 1877–1951)[1] was a Jewish polymath, teacher, writer, researcher, linguist, and collector of rare documents.

Later, during the First World War, he relocated to Madrid where he was appointed in 1915, by royal decree, chair of rabbinic languages and literature After participating in the First Zionist Congress in 1897, A. Yahuda distanced himself from political Zionism.

He discussed the golden age of Jewish culture in Spain, which he aimed to promote as a model for inter-religious relations within a modern political entity.

When reporting on this lecture, Yuval Evri cited the various reactions it provoked, both positive and negative, particularly from Muslim intellectuals (with objections related to the Balfour Declaration of 1917).

[4] In his 1993 play Hysteria, British playwright Terry Johnson created a character partly based on Yahuda's attempt to convince Sigmund Freud not to publish his final book, Moses and Monotheism.
