It may not be common knowledge that Lewis Carroll, author of *Alice in Wonderland* and *Alice Through the Looking Glass*, was “in real life” a mathematician. (I like the story of how the queen, so taken was she with the *Alice* stories, wrote to Carroll expressing interest in any future writing he might do; she was rather nonplussed to receive a textbook on symbolic logic.)

Keith Devlin, NPR’s resident mathematician (wish I had that job…) talks a little about Lewis Carroll the mathematician, and the influence of mathematics on parts of the *Alice* story.
