Mad Hatter : Digital Painting

Although the name “Mad Hatter” was undoubtedly inspired by the phrase “as mad as a hatter”, there is some uncertainty as to the origins of this phrase. Mercury was used in the process of curing pelts used in some hats, making it impossible for hatters to avoid inhaling the mercury fumes given off during the hat making process; hatters and mill workers thus often suffered mercury poisoning, causing neurological damage, including confused speech and distorted vision. Hat making was the main trade in Stockport, near where Carroll grew up, and it was not unusual then for hatters to appear disturbed or confused; many died early as a result of mercury poisoning.

However, the Mad Hatter does not exhibit the symptoms of mercury poisoning, which include "excessive timidity, diffidence, increasing shyness, loss of self-confidence, anxiety, and a desire to remain unobserved and unobtrusive.
