From Wikipedia, the free encyclopedia.
The Hatter, popularly known as The Mad Hatter is a fictional character encountered at a tea party in Lewis Carroll's Alice's Adventures in Wonderland. He makes a cameo appearance in the sequel Through the Looking Glass as "Hatta", the imprisoned royal messenger. He has been portrayed on film by Edward Everett Horton, Martin Short, Ed Wynn and in a music video by Tom Petty.
The phrase "mad as a hatter" existed long before the character, and may derive from the harmful effects of chemicals formerly used in hat making. It has also been said to be a corruption of the phrase "mad as an adder".
The "10/6" on the Hatter's hat is, commonly believed to be the price of the hat. (Ten shillings sixpence)
