Joseph Pearce points out the long list of converts to Catholicism that Lewis, a non-Catholic, influenced.
"On November 22, 1963, at 2:30 pm central
time, John F. Kennedy was assassinated in Dallas. An hour earlier, across the
Atlantic, C.S. Lewis had died at his home in Oxford. A few short hours later,
in Los Angeles, the English writer Aldous Huxley, author of the dystopian
classic Brave New World, would also
die. This strange and somewhat morbid coincidence would later inspire Peter
Kreeft to write Between Heaven and Hell:
A Dialog Somewhere Beyond Death with John F. Kennedy, C.S. Lewis, and Aldous
"The great American literary convert Walker Percy, commenting
on the numerous converts who had come to Catholicism through the writings of
Lewis, remarked that “writers one might
expect, from Aquinas to Merton,” are mentioned frequently as influences, “but
guess who turns up most often? C.S. Lewis! – who, if he didn’t make it all the
way, certainly handed over a goodly crew.”(1) Here is
an overview of some of the “goodly crew” to whom Percy alludes, those who have
been influenced on their paths to Rome by C.S. Lewis. As the present author owes
his own conversion, in part, to the works and wisdom of Lewis, it is gratifying
to know that he is but one of many whom Lewis led Romewards"
