Michel Huglo is known for his more than 200 articles on the history and manuscripts of Gregorian chant, medieval music theory, and early organum. After studying philosophy and theology at the Abbey of Saint-Pierre in Solesmes (1941-47), he was appointed to the Paléographie musicale (1949-60), where he prepared Le Graduel Romain, vol. 2: Les sources. As Chargé de recherche at the CNRS in 1962, then Directeur de recherche in 1972, he travelled extensively to examine early manuscripts; in 1976 he founded the musicology section at the Institut de recherche et d'histoire des textes (IRHT) of Paris. He taught the paleography of medieval music at the École pratique des Hautes Études (Paris IV Sorbonne) from 1973 to 1986, and medieval Latin texts in musicology at the Université libre of Brussels from 1974 to 1987. Appointments followed as Visiting Professor at the University of Vienna (Spring 1990), Visiting Mellon Professor at the Institute for Historical Study of Princeton University (1990-91), and Visiting Professor at New York University (Spring 1993). In 1987 he received the silver medal for research from the CNRS.
As a specialist in the paleography of medieval music, he has concentrated on the sources of medieval monophony, early organum, and music theory. His inventories of processionals and of medieval music theory in German and American manuscripts repertory 1500 sources (RISM B XIV 1-2; RISM B III 3 with C. Meyer; RISM B III 4 with N. Phillips).
