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 ofBatman and Commissioner Gordon the hit went awry and Napier shot Eckhardt in the chest once, killing him.
