H. d' (Henry) Arbois de Jubainville

Born in Nancy on December 5, 1827, Marie Henri d'Arbois de Jubainville was a French historian, philologist, and specialist in Celtic studies. He trained at the École des Chartes as a palaeographic archivist, then spent many years working with the departmental archives of Aube, building a strong reputation as a careful scholar of historical sources.

Later, he became one of the key figures in the academic study of Celtic language and literature in France. He held the chair of Celtic studies at the Collège de France, and his books on early Ireland, Celtic law, and myth helped introduce many readers to medieval Irish traditions and the wider Celtic world.

Remembered for combining archival precision with a deep interest in ancient storytelling, he played an important part in establishing Celtic studies as a serious modern discipline. He died in Paris on February 26, 1910.
