Jean Boucher was a French sculptor based in Brittany. He is best known for his public memorial sculptures which communicated his liberal politics and patriotic dedication to France and Brittany.

Joseph Ernest Renan was a French Orientalist and Semitic scholar, writing on Semitic languages and civilizations, historian of religion, philologist, philosopher, biblical scholar, and critic. He wrote works on the origins of early Christianity, and espoused popular political theories especially concerning nationalism, national identity, and the alleged superiority of White people over other human "races". Renan is known as being among the first scholars to advance the disputed Khazar theory, which held that Ashkenazi Jews were descendants of the Khazars, Turkic peoples who had adopted the Jewish religion and allegedly migrated to central and eastern Europe following the collapse of their khanate.
