Digory Kirke is a character that appears in The Magician's Nephew and The Lion, the Witch, and the Wardrobe

Synopsis
In The Magician's Nephew, Digory is a young boy. Digory's uncle Andrew Ketterley has made magical rings that allows its wearers to travel to other worlds (of completely different universes) by passing through the Wood between the Worlds. Uncle Andrew first tricks Digory's new friend Polly Plummer into trying on the ring. When she disapears Andrew blackmails Digory to try to retrieve her with another ring. After passing through the Wood between the World, Digory breaks an enchantment and accidentally releases Jadis, later the White Witch from her world of Charn. Though she is weak in the Wood Jadis manages to arrive with Diggory and Polly in London, where Jadis causes much commotion. Soon after Digory, Polly, Andrew, Jadis and a cabby driver and his horse end up in the newly born world of Narnia. While there Aslan sends Digory on a journey which allows a magical tree to grow in Narnia, keeping Jadis from attacking Narnia for centuries. He took an apple from this tree, which he used to cure his sickly mother Mabel. He then plants the core, which grows into a magical in his world.

During the events of The Lion, the Witch and the Wardrobe, Digory is seen as the elderly Professor Kirke. His wardrobe is where the Pevensie children enter Narnia. The wardrobe was carved from the tree he had planted as a child, after it had been blown over in a storm. Professor Kirke is the first to believe young Lucy's travels to Narnia, obviously recalling his adventure in the world. However, he never tells the children why he believes Lucy, and the children may have never realized that he had been there, unless Aslan himself told them.

In The Voyage of the Dawn Treader it is mentioned that Digory lost his fortune, which explains why Edmund and Lucy are forced to stay with their cousin Eustance when their parents go abroad.
