“As Mad as a Hatter.”
Have you heard this phrase? Though the EXACT phrase isn’t actually used in Lewis Carroll’s Alice’s Adventures in Wonderland, we know The Hatter’s character as quite mad! It’s beleived that The Hatter’s character was inspired by the mercury poisoning hat makers often suffered from in the 17th, 18th, and 19th centuries (Grammarly Blog, 2015).
Hat makers used mercury nitrate to turn certain furs into felt that was used for the hats they were making (History.com, 2015). Symptoms included slurred speech, tremors, irritability, shyness, depression, and neurological symptoms (CDC, 2010).
Johnny Depp’s 2010 portrayal of Carroll’s Hatter in Tim Burton’s film version of Alice in Wonderland very much played off the symptoms associated with mercury poisoning and is known as The Mad Hatter instead of The Hatter.
