Chrysogonus Waddell (1930-2008) was a monk of Gethsemani Abbey, Trappist, Kentucky, and a scholar of chant and Cistercian liturgy. He studied music composition with Vincent Perschetti at the Philadelphia Conservatory. A convert to Roman Catholicism in 1949, he entered the Abbey of Our Lady of Gethsemani the following year. He was ordained a priest in 1958 and pursued further theological studies in Rome at the College of San Anselmo. Following in the tradition of his fellow Cistercian, Thomas Merton, Father Chrysogonus lived in a hermitage away from the abbey for nearly thirty years. He was choirmaster at the abbey for a number of years. In addition to his compositions, Father Chrysogonus published many scholarly works and translations of monastic and liturgical texts. A widely-recognized chant scholar, and consultor on chant and translations to the International Commission on English in the Liturgy (ICEL), he traveled frequently, presenting at musicological and Cistercian conferences.
