Why was the Mad Hatter mad?
As the Cheshire Cat points out, everyone's mad in Wonderland, and it is true to say that all of the characters are eccentric, at least, and if they weren't, then they wouldn't be there. The phrase "as mad as a hatter" was well known in Lewis Carroll's day, and was a probable inspiration for the character of the Hatter. At the time, many hatters suffered from mercury poisoning. Mercury was a chemical used by hatters to cure felt hats, and the toxic effects of it caused symptoms which resembled 'madness'. Because of this many people assume that the Hatter had mercury poisoning. Whether Lewis Carroll's Hatter actually had mercury poisoning, or if he was just named after the saying is debatable. In Tim Burton's 2010 movie, it is strongly implied that mercury poisoning is the cause of the madness in their depiction of the Hatter.
