Origin
Jervis Tetch began his criminal career disguised as the Mad Hatter due to his obsession with hats and a startling resemblance to the character as depicted in Sir John Tenniel's illustrations from Alice's Adventures in Wonderland.

Captured by the vigilante known as the Batman and his side-kick Robin, Tetch was judged insane and incarcerated in Arkham Asylum.

While incarcerated another criminal calling himself Jervis Tetch assumed the title of the Mad Hatter and began stealing unusual hats for his collection.  Obsessed with stealing Batman's cowl, he was captured by the vigilante and imprisoned.  He would escape on several occasions, employing hats containing weapons to commit his crimes.

Tetch, the original Mad Hatter, escaped Arkham Asylum and claims to have disposed of his imposter, presumably in a murderous fashion, reclaiming his mantle as the Mad Hatter.
