"Mad as a hatter" redirects here. For the Batman episode, see Mad as a Hatter (Batman: The Animated Series). A hatter is a maker or seller of hats.  Milliners are a category of hatters who design women's hats.The origin of the proverbial expression mad as a hatter is uncertain. It may derive from:Robert Crab, a 17th century eccentric who gave all his goods to the poor and lived on leaves and grass.Mercury poisoning suffered by many hatters in the 18th century and 19th century, when mercury was used in the manufacture of felt. Absorption of mercury through the skin can cause Korsakoff's syndrome. These hatters so afflicted were also known as mad hatters.An adaptation of the Anglo-Saxon word atter meaning poison, closely related to the word adder for the poisonous Crossed Viper. Lexicographers William and Mary Morris in Morris Dictionary of Word and Phrase Origins (1977) favour this derivation because "mad as a hatter" was known before hat making was a recognized trade.
