Jeremiah Arkham was the administrator of Arkham Asylum in the early 21st Century.

Jeremiah Arkham

Arkham would inherit Arkham Asylum, but over the course of years, his inability to cure a patient would temporarily lead him into becoming the criminal Black Mask. He would quickly get over this stage and relent, even begin treating Roman Sionis, the first Black Mask. Arkham would be targetted by the Court of Owls, but would be saved by Batman.
