Dodo (Alice's Adventures in Wonderland)

The Dodo is a character appearing in Chapters 2 and 3 of Alice's Adventures in Wonderland, a reference to Charles Lutwidge Dodgson who had a stutter and very frequently pronounced his name :
"Do-do-dodgson".

In this passage Lewis Carroll incorporated references to everyone present on the original boating expedition of July 4, 1862 during which Alice's Adventures were first told, with Alice as herself, and the others represented by birds: the Lory was Lorina Liddell, the Eaglet was Edith Liddell, the Dodo was Charles Lutwidge Dodgson, and the Duck was Rev. Robinson Duckworth.

The dodo is an extinct bird of Mauritius that disappeared in 17th century.
