The 1940s Captain America

This began as a set of MicroHeroes drawn (ahem) from the two-volume reprint of the Simon and Kirby Captain America stories from the 1940s, Captain America: The Classic Years.  However, it's now expanded into all the Cap adventures of the '40s.  As I can find references for the characters, I'll add them.

I've always wondered why Simon and Kirby chose "Camp Lehigh" as the name for Steve Rogers's home base. The stories seem to take place in either metropolitan New York or Washington DC. But "Lehigh" is native to eastern PA (where I used to live), being an Amish corruption of "Lechauweki". Surely Camp Lehigh was not in the Lehigh Valley.  (The Summer 1942 "Vampire" story seems to place Camp Lehigh in California.)

By the way, those who may have seen some of these stories in 1960s reprints in Fantasy Masterpieces may be interested to note that some items acceptable in the '40s were touched up for the '60s. The Butterfly, for example, pierced his victims with his long snout; the reprint implied he just leapt at them and knocked them down. The Hunchback of Hollywood, in his splash panel, was portrayed as a drooling, acromegalic monstrosity, toned down to simpler deformity for the '60s. And Igan and Gorro had their fangs pulled. Igan was redrawn to have two eyes, and Gorro had a rounder, more ape-like face.  O tempora, o mores!
Name Comic Source
Agent X-13 Captain America Comics #1 (March 1941): "Case No. 1. -- Meet Captain America"
Agent X-13 was a young woman masquerading as the aged proprietress of a curio shop.  Behind the shop was the secret lab of the super-soldier project.
unnamed Nazi spy Captain America Comics #1 (March 1941): "Case No. 1. -- Meet Captain America"
This spy snuck into the secret lab as a high-ranking government official.  He killed Prof. Reinstein but died while attempting to flee Captain America.
Professor Reinstein Captain America Comics #1 (March 1941): "Case No. 1. -- Meet Captain America"
Prof. Reinstein developed the super-soldier formula America hoped to use against the Nazi menace.  He was assassinated before making the formula known.
Captain America Captain America Comics #1 (March 1941): "Case No. 1. -- Meet Captain America"
Steve Rogers was an Army reject who volunteered for the super-soldier project as an alternative way of serving his country, being injected with the only sample of the formula.  When the formula sample proved successful, the U.S. government decided to outfit him as a symbol of America and put him to work as a special agent.
Private Steve Rogers Captain America Comics #1 (March 1941): "Case No. 1. -- Meet Captain America"
The newly muscular Steve Rogers was placed into Camp Lehigh as a private, where apparently high officials kept him free from military red tape so that he could act on his own when he saw the need.
Mascot Bucky Barnes Captain America Comics #1 (March 1941): "Case No. 1. -- Meet Captain America"
Camp mascot Bucky Barnes burst in on Steve Rogers as he was changing into his Captain America uniform. In those heady days of wanton child endangerment, Cap decided Bucky had to learn to fight by his side.
Bucky Captain America Comics #1 (March 1941): "Case No. 1. -- Meet Captain America"
Apparently, no one ever associated Captain America's sidekick Bucky with the Bucky of Camp Lehigh, even though Cap operated around Lehigh as often as not.  Chalk it up to those unnamed officials acting as watchdogs.
Sando and Omar Captain America Comics #1 (March 1941): untitled #1
Sando & Omar were the first Cap villains, beyond the origin. Sando was a Nazi agent who hypnotized the idiotic Omar into "predicting" acts of sabotage shortly before they happened.
F.B.I. Agent Betty Ross Captain America Comics #1 (March 1941): untitled #1
Betty Ross was assigned to the Sando and Omar case.  She encountered Cap frequently.  She was apparently dating Sgt. Duffy and had casual contempt for the goldbricking Private Rogers.
Rathcone Captain America Comics #1 (March 1941): untitled #2
Rathcone was a Nazi chess master, manipulating people like chess pieces.
The Red Skull Captain America Comics #1 (March 1941): "The Riddle of the Red Skull"
The Red Skull was a Nazi saboteur and assassin and became Captain America's greatest foe, coming back every few issues.  In his first story, he was unmasked as aircraft manufacturer George Maxon but died from his own methods.  Apparently, as with the Joker, some editor recognized greatness and instructed the artists to resurrect the villain for later use.
Benson and an Ageless Oriental Captain America Comics #2 (April 1941): "The Ageless Orientals Who Wouldn't Die!"
Benson was a banker who discovered the giant Ageless Orientals in the silent Himalayas. They were unable to be killed except by an explosive sound louder than a gunshot.
Adolph Hitler and Hermann Goering Captain America Comics #2 (April 1941): "Trapped in the Nazi Stronghold"
To rescue an influential patriot, Cap and Bucky go to Germany, where, in the course of beating up on generic Nazis, they also got to wallop Adolph Hitler and Hermann Goering. This is the fat Goering as portrayed in the comic. I have no idea what he really looked like.
The Wax Man Captain America Comics #2 (April 1941): "The Wax Statue That Struck Death"

The Wax Man was Mayor Dobbs, a fifth columnist who led a brigade of US-based Nazi soldiers driving Super Tanks based in vast underground bunkers (it says here...). In his spare time, he murdered military commanders either by suffocating them in wax deathmasks of themselves or by kidnapping and decapitating them, keeping their heads in his wax museum.
The Red Skull Captain America Comics #3 (May 1941): "The Return of the Red Skull"
The Hunchback of Hollywood Captain America Comics #3 (May 1941): "The Hunchback of Hollywood and the Movie Murder"
This was a "Phantom of the Opera"/"Clayface I" type of story. A movie production was being sabotaged by a hunchbacked figure.  The Hunchback of Hollywood was handsome actor Craig Talbot, a Nazi sympathizer who opposed the film's anti-tyranny message, and not horror actor "Barloff", who played the hunchback in the film. Quel suprise!
The Butterfly and Lenny Captain America Comics #3 (May 1941): "The Queer Case of the Murdering Butterfly and the Ancient Mummies"
The Butterfly was Dr. Vitrioli, a museum curator who was robbing his own museum. (Why he picked a butterfly as a costumed identity is a mystery. He wasn't stealing butterfly collections...) Lenny was Dr. V's assistant, "a human derrick", one guard called him.
The Unholy Legion Captain America Comics #4 (June 1941): "The Unholy Legion"
The Unholy Legion were a band of fifth columnists masquerading as beggars, street vendors, and general underclass types. Under the command of Herr Snupp, the Beggar Leader, they killed important defense figures and cheated sympathetic Americans who thought they were helping the truly poor and crippled. 

I give you Snupp, who branded both his own agents and law enforcement types (before killing them) with a swastika, and three unnamed murderous beggars: a strangler/news vendor, a cripple with a crutch gun, and a "Poisoned Apple Annie". 

All in all, a rather disturbing class warfare concept, especially so close to the Great Depression.

Ivan the Terrible Captain America Comics #4 (June 1941): "Ivan the Terrible"
Cap and Bucky face Ivan the Terrible, who deposed a kingdom's rightful ruler, just King Peter Ross, and set himself up. After beating Ivan, it turns out... It Was All A Dream!
The Fake Money Fiends Captain America Comics #4 (June 1941): "The Case of the Fake Money Fiends"
Counterfeiters operating in Hillsdale kept snoopers away from the old house that was their base by dressing as ghosts. Seems to me that would have attracted more curiosity than chased it away, but, hey, I didn't grow up in those times. 

Most of these early Cap stories were inspired by movies. If anyone can place the source that first had counterfeiters playing as ghosts, I'd like to know what it was. 

(And they would have gotten away with it, too, if it wasn't for those meddling ...)

Sergeant Duffy Captain America Comics #4 (June 1941): "The Case of the Fake Money Fiends"
While an unnamed sergeant gave Pvt. Rogers a hard time as early as the Rathcone story, this recurring character first appeared in this story.  Privates were often playing practical jokes on the sergeant, and the innocent Pvt. Rogers invariably was blamed for them, probably because Rogers managed to have a true accident involving Duffy every other issue.
Dr. Grimm, Igan, and Gorro Captain America Comics #4 (June 1941): "Horror Hospital"
Dr. Grimm ran a remote private hospital where he kept madmen among his other patients and experimented on all. Igan, here, is one of the doctor's early experiments. 

Dr. Grimm's main experiment was Gorro, a gigantic humanoid monster whom he kept alive with the blood of unwilling donors, usually nurses in Grimm's employ.

The Lord of Death and the Hollow Men All-Winners Comics #1 (Summer 1941): "The Case of the Hollow Men"
The Lord of DeathThe Hollow Man
The self-styled Lord of Death tricked Bowery bums into his lab, where he replaced their blood with his "di-namo fluid", which gave them super-vitality and immunity to death for 24 hours.  (Presumably, after the 24 hours were up, they did die.) He then sent them on destructive missions against US. military suppliers.

The bums were only referred to as "the Hollow Men" in the title.  In the story, they were just "zombies".

Agent Zero, Red Skull Young Allies Comics #1 (Summer 1941): "The Coming of Agent Zero"
The Ringmaster of Death Captain America Comics #5 (August 1941): "The Ringmaster of Death"
He was a Nazi agent whose wheel of chance dictated the night's assassination victim. Other than controlling a circus full of Nazi performers, he had no abilities. Looks a lot like the Hulk/Spidey Ringmaster, though, doesn't he? (Later Marvel stories made him the father of that Ringmaster.)
Captain Okada Captain America Comics #5 (August 1941): "The Gruesome Secret of the Dragon of Death"
Captain Okada commanded a secret weapon of the Japanese navy: the Sea Dragon, a giant, ship-swallowing submarine.
The Bund Captain America Comics #5 (August 1941): "Killers of the Bund"
The Bund was an actual pro-Nazi German-American organization of the WW2 period.  Captain America and Bucky fought some Bund agents who were threatening loyal Americans Hendrich and Bob Shmidt.
Pepo Laroc Captain America Comics #5 (August 1941): "The Terror That Was Devil's Island"
Pepo Laroc was the brutal overseer of Devil's Island, the infamous French prison camp.  He was put in charge by the Vichy government after the Nazis conquered France, so that prisoners of war could experience his cruelty.
The Camera Fiend Captain America Comics #6 (September 1941): "The Camera Fiend and His Darts of Doom"
The Camera Fiend led a gang of crooks who were attempting to steal the British Crown Jewels, which were on tour in America.  His innocent-seeming camera fired poisoned needles.  He was actually Bucky's teacher, Lucius Hall.
The Fang Captain America Comics #6 (September 1941): "Meet the Fang, Arch-Fiend of the Orient"
The Fang was a Chinese warlord, ruler of a tong (a Chinese secret society) in America.  The Japanese Baron Nushima hired his hatchet-men to eliminate two Chinese emissaries seeking a loan from the U.S. to help fight Japanese aggression in China.

While he never appeared again, in the 1960s Cap recalled his having died at Hiroshima.
The Hangman Captain America Comics #6 (September 1941): "The Strange Case of  Who Killed Doctor Vardoff?"
The Hangman systematically eliminated anyone who stood between him and control of the super-strong silk invented by Dr. Vardoff -- and there was quite a list: Vardoff himself, his assistant Ludwig, businessman Dino Cardi, and a mobster's gun moll, all of whom felt the grip of his noose of super-silk.  Actually, the Hangman was Vardoff himself, who wanted nothing more than to be left alone to do his research.
Kuoli and Malay chieftain All-Winners Comics #2 (Fall 1941): "The Strange Case of the Malay Idol" Kuoli Malay Chief Steve Rogers, Bucky, and Col. Carter are stranded on an island in the Malay peninsula when their plane goes down. The pilot, Kurt Mueller, faked the crash in order to get secret documents Carter carried.  As Kuoli, King of the Islands, Mueller commanded a small army of Malay warriors.  
The Red Skull Captain America Comics #7 (October 1941): "Captain America and the Red Skull"
The Skull returns, whisting Chopin's Funeral March as a prelude to his murders.
The Black Toad Captain America Comics #7 (October 1941): "Death Loads the Bases"
The Black Toad was Chuck McArthur, manager of the Badgers baseball team.  Using blowgun darts, he tried to make it appear as if the team was jinxed, so that he could buy it from its current owner at a bargain price.

The Black Toad reappeared in a dream Cap had in issue #18, one of the few villains (besides the Red Skull and Hitler) ever to appear more than once in the 1940s.
The Fiddler Captain America Comics #7 (October 1941): "Horror Plays the Scales"
The Fiddler was a Nazi assassin who used his violin to kill. First, he had an assistant, acting as a servant, put a bomb-laden radio in his victims' homes, which The Fiddler would detonate with certain notes he'd play during a public concert broadcast on the radio. He also could play frequencies that the human system could not stand, but he accidentally killed himself in one attempt, not knowing Cap and Bucky had stopped their ears. 
Pharaoh Ra the Avenger Captain America Comics #8 (November 1941): "The Strange Mystery of the Ruby of the Nile and Its Heritage of Horror"
When Henry Sanders sold a supposedly cursed ruby from an Egyptian tomb, the ruby's new owners began dying at the hands of a seeming spirit of Egyptian vengeance. Cap exposed the fake Pharaoh as Sanders, who couldn't bear to see his treasure in the hands of others. 
Pierre DuMort Captain America Comics #8 (November 1941): "Murder Stalks the Maneuvers"
Pierre DuMort posed as a Major from the Free French forces and led the soldiers of Camp Lehigh into a war game using live ammo. Cap exposed the deception and brought DuMort to justice. 
The Black Witch Captain America Comics #8 (November 1941): "Case of the Black Witch"
The Black Witch tried to keep heiress Karin Lee from her inheritance, Hagmoor Castle (near Camp Lehigh!), by making it appear haunted. The Witch was revealed to be Feritt, the lawyer for the estate, who knew there was oil under the castle grounds. 
The White Death Captain America Comics #9 (December 1941): "Captain America and the White Death"
This was another "kill the heirs" plot, but this time lawyer Matthew Clinton conspired with one of them, knife-throwing son-in-law Manuel Perez, to kill the others and then share the estate. 
Nick Pinto Captain America Comics #9 (December 1941): "Captain America and the Man Who Could Not Die--"
Nick Pinto was sent to the electric chair, but then was arrested committing crimes days later. He was sent to the chair again, after which Cap discovered a conspiracy with a prison doctor to fake Nick's death each time. (My micro is taken from the splash page image of Nick; in the story, he appeared as a normal human.) 

Like many Simon/Kirby stories of the '40s, this was inspired by a movie, Lon Chaney Jr.'s Man Made Monster.

The Black Talon Captain America Comics #9 (December 1941): "The Case of the Black Talon"
The Black Talon was artist Pascal Horta, whose right hand (his painting hand) was crushed in a car accident. A surgeon transplanted the hand of Strangler Burns, a Black murderer who wanted to atone by donating his body to science, to the artist. The artist then claimed "the corpuscles of the dead killer's hand invaded my blood-stream -- slowly seizing control of my brain", forcing him first to paint, and then to create, scenes of death.

Inspired by the film The Hands of Orlac, or more likely its later remake with Peter Lorre, Mad Love, neither of which used the race angle. Dunno who's to blame for that one. 

The Artist All-Winners Comics #3 (Winter 1941): "The Canvas of Doom" Artist The Artist paints portraits of people killing themselves, using paint laced with an hypnotic drug, so that the viewer is forced to act on the image.
This is one of the first Cap stories not drawn by the Simon/Kirby team, as they had left Timely over varous issues.  Al Avison apes the Simon/Kirby style in layout, if not the details of the art.  Story is by "S.T. Anley", i.e., Stan Lee.
Black Talon, Baron Boche Young Allies Comics #2 (Winter 1941): "Fate Spins an Evil Web"
I know nothing about this reappearance, other than he fought Bucky's Young Allies team.

The Black Talon also later turned up in Cap's dream in #18, making him Cap's only three-timer from the '40s. 
Countess Mara Captain America Comics #10 (January 1942): "Spy Ambush"
Countess Mara led a team of spies to steal a new rapid-fire grenade gun. 
Netman Captain America Comics #10 (January 1942): "Hotel of Horror"
The Netman, a fifth columnist, learned Cap was to be honored by an American city (Gotham City!) and, posing as Charley Boswell, the Mayor's secretary, led Cap into a hotel in that city filled with traps and killers. 
The Hound Captain America Comics #10 (January 1942): "The Phantom Hound of Cardiff Moor"
The Hound was supposedly an ancient spectre, cursing those who lived in Cardiff Manor after the original owners were forced out. He was really Mr. Murdock, the last of the original owners who, in conjunction with a phosphorus-painted mastiff, sought to reclaim the manor from recent buyers. 

Yeah, yeah, The Hound of the Baskervilles. Again, "Cardiff Moor" was supposed to be somewhere near Camp Lehigh. This is the last published Simon/Kirby Cap story.

feuding mountaineers Captain America Comics #11 (February 1942): "The Feud Murders"
Mephisto Captain America Comics #11 (February 1942): "The Symphony of Terror"

The Vulture Captain America Comics #14 (May 1942): "The Horde of the Vulture"

Fritz Krone Captain America Comics #15 (June 1942): "The Tunnel of Terror"

Dr. Togu, the Vampire
Dr. Togu was "the world's greatest master of occult medicine" who distilled the secret of vampirism into a formula, which he drank.  As the Vampire, he preyed on American Army officers, until Cap knocked him into sunlight, whereupon he reverted to human form and fell to his death.

Agent Axis Tales of Suspense #82 (October 1966): "The Maddening Mystery of the Inconceivable Adaptoid!"

[actually, Boy Commandos #1 (Winter 1942-43): "Satan Wears a Swastika"]

Agent Axis
The Adaptoid, a shape-changing android, imitates a number of Cap's old foes, including "Agent Axis!  The scourge of World War Two!"

Unfortunately, the story's artist, Jack Kirby, forgot that it was his Boy Commandos, for rival DC, who had actually fought Agent Axis in the '40s.  It took Roy Thomas, in the 1970s, to come up with the story of the Marvel version of Agent Axis, a bizarre three-bodies in-one fusion of Axis spies.
