|The Atom Man|
A different version of the Atom Man was also the villain in Atom Man vs. Superman, the second live action Superman serial.
The Adventures of Superman (Radio)
The Atom Man was created by the evil Nazi scientist Der Teufel in 1945, as part of his dream to finally destroy Superman and conquer the world. The concept was simple to Teufel: use the Kryptonite stolen from the Scarlet Widow; convert the Kryptonite to liquid and inject it into a test subject; and use a special converter box on the throat and meshed gloves of platinum and thorium. The converter, when switched, would flash to the Kryptonite in the bloodstream, "rearranging the outer structure of the atoms," and when they reach the gloved hands, "the nucleus of the atom is broken, and there will emerge from his fingers a stream of energy such that anything in its path - be it men, or great buildings, or even mountains, will disappear as if they had never been there!"
That subject was one Heinrich Milch, the son of chemist Professor Milch (who dissolved the Kryptonite). Though born in Germany, Milch moved to the United States where he was educated in Metropolis, studying journalism under the name Henry Miller. When World War II broke out, Milch returned to his homeland, although his German accent was by then lightened through his American schooling. Now a young adult, Milch "did well in the war" and received the Iron Cross from Adolf Hitler himself. Milch/Miller is described as a slim, blond German youth, who women (such as the Daily Planet receptionist Miss Barton) find attractive. Milch volunteered for the Atom Man project, with his father's encouragement and approval. However, when the experiment seemed to fail and Heinrich lay seemingly lifeless, a grief-crazed Professor Milch threatened to expose Teufel to the occupying Americans. Teufel sought out and murdered the chemist. When the young "Atom Man" revived however, Teufel blamed the elder Milch's death on the Americans, further fueling the youth's enmity towards the Allies.
Atom Man vs. Superman (Film Serial)
The Atom Man, in a markedly different form, was the title villain of the second Superman film serial, Atom Man vs. Superman. Here, however, Lex Luthor is the alter-ego, initially presenting the Atom Man as his "friend and partner." Luthor dons a metallic mask and black cloak and speaks in a foreign accent, but possesses no powers beyond his own intellect and cunning. Kryptonite, which figured heavily in the first Superman serial, is absent. Instead, the Atom Man's name reflects Luthor's technology, capable of reassembling or dispersing atoms.
In the post-Crisis timeline of Superman & Lois, Henry Miller was a neo-Nazi who lived in the "Little India" neighborhood of Lower Metropolis and worked at the "USA First Hardware" store. As properties in his neighborhood were bought in increasing numbers by non-white immigrants, he started setting fire to their businesses while dressed in a metal mask and trench coat, and tagged their properties with the symbol of the "Schutzstaffel".
The Daily Planet journalist Lois Lane had tried learning his identity, but her work researching information on him was ignored by her editor Perry White, due to more importance being given in the news to a newly-arrived superhero, who unknown to her was her co-worker Clark Kent in disguise. After learning how he and his heroics was responsible for it, Clark offered to help her and she agreed.
Clark and Lois after investigating eventually narrowed down the attacker's identity to a list of suspects. Miller was soon arrested by the police and his identity as the arsonist exposed, but he was quickly released. He decided to attack again in retaliation, but this time in a lethal manner by directly targeting minority people and killing them.
After Lois learned about what Miller was doing from her source, she went to confront him and urged him to stop. Miller however ignored her pleas and attacked her with a flamethrower, but Clark soon arrived in his superhero disguise to save her after learning about the confrontation between the two. Miller then tossed hand grenades at people, but Clark prevented them from harming anyone. Lois then took advantage of Miller being distracted due to his fight with Clark and tasered him.
