Reginald Cuthbert Fuller (12 September 1908 – 21 April 2011) was ordained as a priest in 1931 by Cardinal Bourne, Roman Catholic Archbishop of Westminster, and appointed Canon (hon.) of Westminster Cathedral by Cardinal Murphy-O'Connor in 2001. He celebrated his 100th birthday in 2008.
Born in London, he contributed significantly to the advancement of Roman Catholic life and ecumenism in England during the 20th century, notably through co-founding the Catholic Biblical Association of Great Britain, his collaboration as an Editorial Committee member of the first one-volume Bible commentary for English-speaking Catholics and his General Editorship of its second edition, and his work as a member of the Revised Standard Version Bible Committee and as Co-Editor of the first complete Bible translation in modern English for Catholics from the Hebrew and the Greek, as well as of its ecumenical edition. His specialist subjects were the Deuterocanonical Books, on which he contributed articles to three major Biblical Commentaries (see "Publications" below), and the life and works of Alexander Geddes, a pioneer of biblical criticism, on which he wrote his doctoral thesis (see "Publications" below).
Initially Fuller's parents, the physician and medical author Arthur William Fuller and Florence Margaret Fuller (née Montgomery), of St John's Wood, London, sent their son to Ealing Priory School (subsequently renamed St Benedict's School) where he happened to share classes and hone his Latin skills in competition with a younger pupil, later also a New Testament scholar who would be Fuller's colleague on a number of major academic projects, John [Bernard] Orchard. Recognizing his academic potential, they then decided to move their son to Cardinal Vaughan School, before sending him for the final years of his schooling to Ampleforth College.
