Mad Hatter

The Mad Hatter is a character from Lewis Carroll's "Alice's Adventures in Wonderland." He is known for his eccentric behavior and bizarre tea parties, alongside the Cheshire Cat and the March Hare. The term "mad as a hatter" refers to someone who is completely crazy, which likely originates from the historical use of mercury in hat-making, causing mental illness among hatters. The character reflects themes of absurdity and nonconformity, showcasing the whimsical and often nonsensical nature of Wonderland. His iconic top hat and playful dialogue have cemented him as a symbol of madness and creativity in literature.
