Mathematician:Charles Lutwidge Dodgson

Mathematician
English mathematician and logician, Anglican priest and author of children's books.

He is best known nowadays for his Alice's Adventures in Wonderland and Through the Looking-Glass, and What Alice Found There, not (on the surface) works of mathematics.

His actual mathematical works tended to be idiosyncratic, often focused on making mathematical concepts (in particular, logical syllogisms) accessible to children.

One of the first to treat logical elements with symbols, thus contributing to the birth of symbolic logic.

The surname Dodgson is pronounced Dodson.

Also known as
Charles Dodgson was far better known as Lewis Carroll, the nom de plume under which he wrote his works for children.

It has been suggested that Lewis Carroll can be considered to be a modernisation of le wis carle, which is approximately old English for the wise man.

However, the alias actually arises from:
 * A variation of Lutwidge for Lewis
 * The Latin form of Charles (that is, Carolus) for Carroll.
