Lt. Max Eckhardt was a plain-clothes detective with the Gotham City police department. Slimy and corrupt, he was in the pay of Carl Grissom. Eckhardt was ordered by Grissom to kill his treacherous right-hand man Jack Napier at Axis Chemicals, but thanks to the intervention of Batman and Commissioner Gordon the hit went awry and Napier shot Eckhardt in the chest once, killing him.
