Who's Who in Gregorian Chant
“When a large number of manuscripts of various epochs and from different countries agree in the version of a chant, it may be affirmed that those manuscripts undoubtedly give us the phrase of St. Gregory.” (Dom Guéranger, Institutions liturgiques)
“Never is there one result among many chances. Error should have been varied . . . . Whatever is found to be one and the same among many is not an error but a tradition.” (Tertullian)

Note: This list includes people associated with the restoration of Gregorian chant who have published, edited, translated, recorded, or developed websites about chant. By restoration is meant the modern period beginning with the work of Fr. Lambillotte and Dom Gueranger; therefore historical figures such as Hucbald, Notker, or Guido have not been included. Out of respect for conventions, there is some deliberate inconsistency in the use of honorifics. Academic titles are not used for clergy or religious. Dom is used for solemnly professed monks of the Solesmes, English, and Beuronese congregations and supersedes titles such as Prior or Abbot; Fr. (Father) or Br. (Brother) is used for monks of other Benedictine congregations. In most of Europe, professors must have completed a habilitation or post-doctoral qualification, which involves work equivalent to a second doctorate. In the United States, Dr. is generally regarded as higher than Prof. (one of my teachers recalled that in the previous generations, it was not especially uncommon for someone with only a bachelor's degree to hold a full professorship).
