Mad As a Hatter

If someone says you are mad as a hatter, they are accusing you of being quite irrational. The sense of madness here is "suffering from a disorder of the mind; insane." This phrase usually refers not to someone who is actually insane, but rather to a more normal person who is behaving in an irrational way.
The phrase emerged in England in the 19th century. Hatmakers in those days used a lot of felt that was treated with chemicals including lead, arsenic, and mercury.
Unfortunately, those chemicals are highly toxic. The symptoms of such poisoning include palsy, confused speech, and distorted thinking. Today, making hats is a much safer profession, but the phrase survives.

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
