Wycliffe Bible
Authorship has never been conclusively defined, but its popularity in its day is undisputable, evidenced by the nearly 200 manuscripts extant, most of them copied between 1420 and 1450. Separate books surfaced between 1382 and 1395 and it is safe to conclude that several people have been working on these books, which culminated into what is now know as the Wycliffe Bible. Scholars hold John Wycliffe to have been the author of the Gospels. Wycliffe died on New Year's Eve of 1384 - over a decade prior to the surfacing or completion of the last books. Another  contributor is believed to have been Nicholas of Hereford. One of the early manuscripts contains a closing note in the book of Baruch (Bodl. Douce MS. 369), stating "Here ends the translation of Nicholas of Hereford." Hereford survived Wycliffe by several decades, and was an active member of Wycliffe's movement until the near-final years in which the last manuscripts appeared. A third scholar considered to have played a major role is John Purvey, who is believed to have been instrumental in improving the readability of the English, as this very first complete translation in its primal edition was too literal to be properly readable. All three men, Wycliffe, Hereford and Purvey, were graduates of Oxford University.
