Did you know...
Charles Dodgeson

Our logo is the Cheshire Cat introduced by Charles Dodgson (1832-1898) in the book Alice's Adventures in Wonderland. Charles wrote the Alice in Wonderland books under the pseudonym Lewis Carroll. Charles Dodgson was an excellent mathematician who worked in the fields of algebra, geometry, matrix algebra and mathematical logic.

At one point in the book, Alice sees the Cheshire Cat sitting in a tree, and the cat disappears until only its grin is left. At another point, when the Queen decides to cut off its head, it disappears leaving only the head, causing the executioner a real problem.
