C. S. Lewis became internationally famous by the time he published the first of seven Narnian books. But he was already famous in England.
During World War II, his voice was the second-most-recognized voice of the BBC (after Winston Churchill), through a series of live broadcasts he conducted beginning in 1941. The book published today as Mere Christianity originally aired as live, 15-minute radio broadcasts. In fact, the first part of the book (The Case for Christianity) was published in England as Broadcast Talks.
Diligently trying to answer letters, Jack "met" a bright American woman whose penetrating, thoughtful analysis impressed him. Joy Davidman Gresham was capable of matching wits with the famous writer - a skill not many people could claim.
Joy, the mother of two young sons, possessed intellectual insight coupled with a straightforward, get-to-the-point manner. A Jewish communist, she had converted to Christianity largely on the basis of Jack’s analytical writings. Although she did not agree with all his points, she publicly credited Jack with helping her rethink her religious beliefs. She also helped him rethink his romantic life.
