Dictionary of National Biography, 1885-1900/William of Chester
WILLIAM of Chester (fl. 1109), poet, was a pupil of Anselm, probably at Bec, and became a Benedictine monk of Chester, which was founded from Bec in 1092. He wrote a poem addressed to Anselm on his elevation to the see of Canterbury, which Anselm acknowledged in Ep. iii. 84, and also an Epicedion in elegiacs on his death, printed in Baluze's ‘Miscellanea,’ iv. 15. He is probably to be distinguished from the abbot of Chester who ruled 1121–1140.
