Clive Staples Lewis commonly referred to as C. S. Lewis and known to his friends and family as "Jack", was an Irish-born British novelist, academic, medievalist, literary critic, essayist, lay theologian and Christian apologist. He is well known for his fictional work, especially The Screwtape Letters, The Chronicles of Narnia and The Space Trilogy.
Lewis was a close friend of J. R. R. Tolkien, and both authors were leading figures in the English faculty at Oxford University and in the informal Oxford literary group known as the "Inklings". Wartime radio broadcasts on the subject of Christianity brought him wide acclaim.
In 1956, he married the American writer Joy Gresham, 17 years his junior, who died four years later of cancer at the age of 45.
Lewis died three years after his wife, as the result of renal failure. His death came one week before his 65th birthday. Media coverage of his death was minimal, as he died on 22 November 1963 – the same day that U.S. President John F. Kennedy was assassinated, and the same day another famous author, Aldous Huxley, died.
Lewis's works have been translated into more than 30 languages and have sold millions of copies. The books that make up The Chronicles of Narnia have sold the most and have been popularised on stage, TV, radio and cinema.
