Mad Hatter?

Question

Does anyone know the poem that explains why the Mad Hatter is Mad? If so please post

Answer 1

The stuff that made the hatter mad—

Can mercury be all that bad?



Can heavy mirror globes of light

Become a foe of thinking right?



Can sprightly silver droplets kill,

Or trim IQs to nearly nil?



Alas, the metal’s bad for lungs

And puts strange tastes upon our tongues.



It harms the kidneys and the skin

And babes, of pregnant moms, within.



Especially is it the bane

Of healthy-working nerves and brain.



So treat thermometers with care,

Lest vexing vapors foul the air.



That power plant upwind can make

A poison bath of stream or lake.



Beware that large and tasty fish

Become, when served, a risky dish.



And may your home and table be

Completely free of mercury!

Answer 2

The book that mentions the Mad Hatter is "Alice in Wonderland". The sequel is "Through the Looking Glass"

Both are by Lewis Carroll

Answer 3

"Mad as a hatter" became a common term for someone experiencing severe mental problems. I hope this helps.
