Herbert John Davis (1893-1967) was a scholar of 18th-century English literature. He spent much of his academic career in Canada and the USA, but returned to Britain in 1949 as Reader in Bibliography and Textual Criticism at Oxford. Davis's most significant publication was his definitive edition of Jonathan Swift's prose, The prose works of Jonathan Swift, which he began in 1939. See Who Was Who for further details.
