The Trinity Gower D Scribe, often referred to simply as Scribe D, was a professional scribe and copyist of literary manuscripts active during the late fourteenth and early fifteenth century in London, England. Although his real name long remained unknown, Scribe D has been described as "so well known to students of late Middle English manuscripts that he hardly needs any introduction".

Thomas Hoccleve or Occleve (1368/69–1426) was a key figure in 15th-century Middle English literature, significant for promoting Chaucer as "the father of English literature", and as a poet in his own right. His poetry, especially his longest work, the didactic work Regement of Princes, was extremely popular in the fifteenth century, but went largely ignored until the late twentieth century, when it was re-examined by scholars, particularly John Burrow. Today he is most well known for his Series, which includes the earliest autobiographical description of mental illness in English, and for his extensive scribal activity. Three holographs of his poetry have survived, and he also copied literary manuscripts by other writers. As a clerk of the Office of the Privy Seal, he wrote hundreds of documents in French and Latin.
