Asteroid 6735 Madhatter was discovered on November 23, 1992 at the Oohira unit of Nihondaira Observatory near Shimizu, Shizuoka, Japan, by Japanese astronomer Takeshi Urata. It has a period of 3 years, 62 days. Urata named the asteroid for a character from Lewis Carroll, the Mad Hatter.
"Mad as a hatter" is a venerable English expression which probably arises from the fact that old-time hatters, or hat makers, were subject to dementia and other neurological symptoms arising from mercury poisoning which was contracted by handling felt, which was routinely manufactured using mercury compounds.
It is this that seems to give rise to Madhatter's astrological meaning, madness.. Alice Cooper frequently wears top hats on stage, as does another shock rocker, Marilyn Manson.
