Donatien de Bruyne (1871–1935) was a French biblical scholar, textual critic, and Benedictine. He was born on 7 October 1871 in Neuf-Église, ordained in 1895. De Bruyne examined Latin manuscripts of the Vulgate, and he collated some of the manuscripts (e.g. Codex Frisingensis, Codex Carinthianus). De Bruyne questioned Jerome's authorship of the Pauline epistles of Vulgate. According to him Pelagius prepared the Pauline epistles. De Bruyne discovered and published in 1930 an anti-Marcionist Prologue to the Gospel of John.
