'''Alger of Liège''' ([[1055]]-[[1131]]), known also as Alger of Cluny and Algerus Magister, a learned [[France|French]] [[priest]] who lived in the first half of the [[12th century]].

He was first a [[deacon]] of the [[St Bartholomew's Church, Liège|church of St Bartholomew]] at [[Liège (city)|Liège]], his native town, and was then appointed (c. 1100) to the cathedral church of [[Lambert of Maastricht|Saint Lambert of Maastricht]]. He declined many offers from German bishops and finally retired to the monastery of [[Cluny]], where he died at great age and leaving a good reputation for piety and intelligence.

His History of the Church of Liège, and many of his other works, are lost. The most important of those still extant are: 1. ''De Misericordia et Justitia'', a collection of biblical and patristic extracts with a commentary (an important work for the history of church law and discipline), which is to be found in the Anecdota of Martene, vol. v. 2. ''De Sacramentis Corporis et Sanguinis Domini''; a treatise, in three books, against the [[Berengar of Tours|Berengar]]ian heresy, highly commended by [[Peter of Cluny]] and
[[Erasmus]]. 3. ''De Gratia et Libero Arbitrio''; given in B. Pez's ''Anecdota'', vol. iv. 4. ''De Sacrificio Missae''; given in the ''Collectio Scriptor. Vet.'' of Angelo Mai, vol. ix. p. 371.

See [[Jacques Paul Migne|Migne]], ''[[Patrologia Latina|Patrol Ser. Lat.]]'' vol. clxxx. coll. 739-.972; Herzog-Hauck, ''Realencyk. für prot. Theol.,'' art. by S. M. Deutsch.
