5 NOTES

1. He’s Based on Real “Madness”! The phrase “mad as a hatter” comes from 18th- and 19th-century hat makers who were poisoned by mercury used in hat making, which caused tremors and hallucinations.
2. His Tea Party Never Ends! 
In Alice's Adventures in Wonderland, the Hatter is stuck 
in a perpetual tea party 
because Time has stopped 
for him—literally!
3. He’s Not Actually Called “Mad Hatter” in the Book! Lewis Carroll only ever calls him the Hatter—
the word “mad” is added by 
the Cheshire Cat.
4. The Number on His Hat Has Meaning! The price tag on his hat reads “10/6,” which means ten shillings and sixpence, the cost of the hat in Victorian England.
5. Tim Burton Gave Him a Dark Backstory! In the 2010 movie, Johnny Depp’s version of the Hatter has a tragic past and uses his wild personality as a way to cope with trauma.
