Sir Thomas Malory (c. 1415-18 - 14 March, 1471) was an English writer of Arthurian romances. He is generally identified as Sir Thomas Malory of Newbold Revel in Warwickshire, a knight, land-owner, and Member of Parliament.
Malory was arrested in 1460 and imprisoned in Newgate prison, where he wrote Le Morte Darthur. Sir Thomas Malory died in prison in 1471, with Le Morte Darthur being published posthumously in 1485.
A previously unknown manuscript copy of Malory's work was discovered at Winchester College in June 1934. Eugène Vinaver examined the manuscript, and concluded that Malory wrote a series of Arthurian tales, not a single book. Vinaver published an edition of Malory's works, based on the Winchester Manuscript, in 1947.
