Alcuin of York (Latin: Flaccus Albinus Alcuinus; c. 735 – 19 May 804 AD)—also called Ealhwine, Alhwin or Alchoin—was an English scholar, clergyman, poet and teacher from York, Northumbria. He was born around 735 and became the student of Archbishop Ecgbert at York. At the invitation of Charlemagne, he became a leading scholar and teacher at the Carolingian court, where he remained a figure in the 780s and '90s.
Alcuin wrote many theological and dogmatic treatises, as well as a few grammatical works and a number of poems. He was made Abbot of Tours in 796, where he remained until his death. "The most learned man anywhere to be found", according to Einhard's Life of Charlemagne (ca. 817-833), he is considered among the most important architects of the Carolingian Renaissance. Among his pupils were many of the dominant intellectuals of the Carolingian era.
