Professor Erlich was an archeologist and teacher at an undisclosed university.
Erlich was once a colleague of Felix Faust, and one of the professors who mocked him for his heretical ideas.
Seeking information on Faust, Batman confronted Erlich on a rainy evening outside the academy building. Intimidated by and terrified of the Dark Knight, he told him everything he knew.
