Must be some interesting things about him, surely?
Although he is remembered for his children's literature he is remembered for, among his talents were mathematics, invention (including a Nyctograph, a device to record, Braillelike, any thoughts during the night without getting out of bed), word and chess puzzles and had remarkable skill with the camera when the craft was in its infancy, having his work shown at London's annual Photographic Exhibition.
He was a devout member of the Church of England, ordained a Deacon though seldom preaching because of his stammer. And he had an affinity for Tuesdays.
Alice in Wonderland was not just written for one girl, but for three  Alice Liddell and her two sisters. They contain many mathematical twists, word plays, political caricatures and injokes. Although Alice was the heroine (incidentally, the Alice of Tenniel's drawings is not Alice Liddell, who had short, dark hair) the three also had a joint role as the three sisters who lived in the treacle well, the names being puns or distortions of the originals, for example Lacie for Alice (an anagram).

Go on then, give us a clue...

It's a photograph of Alice Liddell as an adult. Here's one of Dodgson's versions of her as a child:

CL Dodgson was one of the founders of acturial maths, used to calculate life insurance premiums & pensions

Wiki says it was Christ Church.
Quote:  Through his own laziness, he failed an important scholarship, but still his clear brilliance as a mathematician won him the Christ Church Mathematical Lectureship, which he continued to hold for the next 26 years.

 Symbolic Logic and The Game of Logic are still in print as one volume. I borrowed from a library, I suppose about 15 years ago. They contained lots of amusing convoluted syllogisms, and some diagrams which were a little like Karnaugh maps, if I remember correctly

There is a story that Queen Victoria read Alice in Wonderland and liked it so much that she asked for more books by the same author. She was then sent a book on symbolic logic.

They contained lots of amusing convoluted syllogisms, and some diagrams which were a little like Karnaugh maps, if I remember correctly  You do indeed remember correctly. At the end of Symbolic Logic, he gives a foretaste of Parts II and III, including:
* several problems which have premisses involving 3 or 4 of the variables (e.g. "A man, who neither gambles not eats porkchops for supper, is sure to have a ravenous appetite") and
* one problem which appears to involve a 3value logic (e.g. "some of the Monitors are awake" and "some of the Monitors are asleep" are used, indicating that we must account for any of 3 possibilities: all awake, all asleep, some of each)
Carroll did a considerable amount of work on Part II, and what exists, together with the complete Part I, was published by Harvester Press in 1977 (ed. William Warren Bartley, III). Part II describes Carroll's algorithm (not entirely systematic) for solving such problems.

There is a story that Queen Victoria read Alice in Wonderland and liked it so much that she asked for more books by the same author. She was then sent a book on symbolic logic.  Sometimes the story specifies that the Queen asked for the author's next book, and that he sent her On The Condensation of Determinants. The story is false, and Dodgson repudiated it.
BTW if you do decide to use Dodgson in QI, please note that the g is silent. In Dodgson's lifetime, sometimes people got his name wrong, but the mistake was the other way around: people knew the pronunciation but misspelt the name as Dodson.

How do you pronounce Lutwidge?

I've always heard it pronounced and pronounced it Ludwig. I'm QE though (not Queen Elizabeth, but like her, being Quite English). I suppose a dastardly hun might slurrr it into LudViTCH.
