Derek Stanley Brewer (13 July 1923 – 23 October 2008) was a Welsh medieval scholar, author and publisher.
Born in Cardiff, Wales, the son of a clerk with General Electric, Brewer read English at Magdalen College, Oxford, where he was taught, among others, by C. S. Lewis.
He served as infantry officer with the Worcestershire Regiment and with the Royal Fusiliers during World War II, from 1942 to 1945, then returned to Oxford.
He died in Cambridge, England, a month after the death of his wife Elisabeth.
Obituaries in all the main British newspapers and blogs in the US speak highly of his love of literature and the profession,[4] his advocacy of struggling academics of the medieval period to get their work published,[5] his encouragement of female students (a rarity in the medieval field during much of his lifetime),[5] and his courtesy and friendliness.
