What were the initials represented by the name C.S. Lewis?

The initials in C.S. Lewis’s name represented Clive Staples. He was born Clive Staples Lewis in Belfast, Ireland, on 29 November 1898.

Lewis was commonly called “Jack” by family and friends, a nickname that arose during his childhood after the death of a childhood pet. “C.S. Lewis” became the professional name under which he published fiction, literary criticism, Christian apologetics, and autobiography.

His middle name, Staples, came from his mother’s family. The name is sometimes mistakenly expanded using other C names, but authoritative biographies and Lewis’s own published identity give his full name as Clive Staples Lewis.

Lewis later became one of the twentieth century’s best-known Christian writers. His major works include The Chronicles of Narnia, Mere Christianity, The Problem of Pain, and The Four Loves.
