Walton Hannah

William Walton Thomson Hannah (1912, Sussex – February 1966) was an Anglican clergyman who converted to Roman Catholicism and who wrote the book Darkness Visible.

In January 1951 Hannah wrote an article "Should a Christian be a Freemason?" in Theology, a magazine produced by the Society for Promoting Christian Knowledge. This was controversial, as both the King and Geoffrey Fisher, the Archbishop of Canterbury, were Freemasons, as were many Anglican clerics. The Church of England Assembly discussed the subject in June 1951, although there was no substantive conclusion.

Darkness Visible was published in 1952. He later published Christian by Degrees, left England for Canada and became a Roman Catholic priest.
