Today is National Felt Hat Day.
Hat Trivia: The phrase “a mad as a hatter” comes from the use of mercury nitrate in haberdasheries in the late 18th and early 19th centuries. Over time, daily exposure to this metal caused these tradesmen to develop dementia, tics and other symptoms. These unusual side effects caused people to believe their hatters had gone mad.
