Warren Lewis

Their lifelong friendship was formed as the boys played together in their home on the outskirts of Belfast, Little Lea, writing and illustrating stories for their fantasy world of Boxen (a combination of India and a previous invention called Animal-Land).

In 1908, their mother died from cancer and as their father mourned her, C. S. ("Jack") and Warren Lewis had only each other for comfort and support.

On 10 September 1913, Warren Lewis began studying privately with William T. Kirkpatrick for four months in preparation for the entrance examination of the Royal Military College, Sandhurst.

After World War II, he took up residence with his brother at a house named The Kilns at Headington, near Oxford, where he lived until the death of C. S. Lewis in November 1963.

During the 1930s, the Lewis brothers undertook eight annual walking tours of as many as 50 miles (80 km), which Warren years later recalled with fondness, saying, "And jolly good fun they were too."

According to Douglas Gresham, his step-nephew,[6] and his brother's letters to Arthur Greeves,[7] Warren Lewis was an alcoholic.

Warren Lewis was buried in the churchyard of Holy Trinity Church, Headington, Oxford,[8] where he is interred in his brother's grave.
