What was the name of C.S. Lewis's older brother and longtime memoirist?
Answer
Warren Lewis
C.S. Lewis's older brother and longtime memoirist was Warren Lewis.
Warren Hamilton Lewis was born in 1895, three years before his brother Clive Staples Lewis. The brothers shared a close relationship throughout their lives, despite periods of separation caused by schooling, military service, and academic work.
Warren served in the British Army during the First World War and later became a historian. He lived with C.S. Lewis for many years at The Kilns near Oxford and helped preserve and organize family and personal records.
Warren is also associated with the Inklings and kept diaries that provide valuable evidence about Lewis's daily life. Readers sometimes confuse him with Albert James Lewis, C.S. Lewis's father, or with Lewis's literary friends such as J.R.R. Tolkien. Warren was Lewis's brother, not his father or fellow author in the same sense.
