History in print
In his first appearance in Detective Comics #66, the character's name is Harvey Kent, but in later stories his last name is changed to Dent to prevent confusion with Clark Kent, the alter-ego of Superman.

The character only made three appearances in the 1940s, with his last appearance showing his scarring fixed and therefore his sanity restored. He made only two appearances in the 1950s, with others taking the Two-Face name in his absence.

In 1968, he appeared in World's Finest Comics #173, where it is revealed that Two-Face is the criminal he most fears, and in 1972 Dennis O'Neill brought Two-Face back to be an arch-enemy of Batman.

In 1986, Frank Miller's Batman: Year One revised Batman's origin and showed Harvey as a major heroic figure and one of Batman's earliest allies. Andrew Helfer changed Harvey's to match. In Batman Annual #14, it is revealed that Harvey had an alcoholic, abusive father, had bipolar disorder and struggled with paranoia.
