Notker Labeo

Notker Labeo (c. 950 – 28 June 1022), also known as Notker the German (Latin: Notcerus Teutonicus) or Notker III, was a Benedictine monk active as a scholar and teacher. He was the first commentator on Aristotle active in the Middle Ages and translated the works of earlier Latin writers such as Boethius and Martianus Capella. Notker is also attributed the authorship of five short essays on music. Labeo means 'the thick-lipped one'.
