Earth-E Timeline

Earth-E was first postulated by Mark Gruenwald in Omniverse #1, 1977. Its role 
was to deal with the "Super-Sons" series which appeared in several issues of 
World's Finest, starting from issue 215: 

"Between the Earth-Two Superman and Batman whose careers began in the 1940's 
and the Earth-One and Batman whose careers began in the 1960's, there must have 
been a Superman and Batman whose careers began in the 1950's. In scanning the 
complete runs of all the magazines where Superman and Batman regularly appeared, 
is it difficult to assign strict cut-off points where one Earth's heroes' 
adventures end and the next begins. Still, let us presume that the period between 
the retirement of the Justice Society (All-Star #57, February-March 1951) and the 
founding of the Justice League (Brave & Bold #28, February-March 1960) roughly 
corresponds to the heyday of the Earth-E heroes." 

"The 'E' stand for both 'Extraneous' and 'E.' Nelson Bridwell, who first postulated
the existence of this 'middle Earth.'"

Detailed sites on these characters can be found at Operation Super-Sons and at
The Far-Out Saga of the Super-Sons.

[Note from Mikel Midnight: of course Gruenwald's dates are slightly off.  The 
Earth-2 World's Finest team started their career in the 30's and the Earth-1 
heroes must have been established by the late 50's (pace floating Earth-1 
timescale), so the Earth-E heroes must have started their careers in the 40's.]

Mid 1940s
 Superboy is blackmailed by the Invisible Empire, alien invaders who can 
disassemble their atomic structure and plate themselves onto any object, and 
who have disassembled the molecules of everyone in Smallville.  The aliens 
threaten to keep the people of Smallville in this state unless Superboy brings
them the Earth's leaders for them to occupy. Superboy tricks them into
accepting robotized wax dummies of the world's leaders (Adolf Hitler, Benito 
Mussolini, Winston Churchill, Josef Stalin, Hirohito, and Vidkun Quisling) 
as new body-homes and, after they bring back the people of Smallville, has a 
robot Anton Mesmer hypnotize them into eternal sleep.  One last alien remains, 
but Superboy manages to imprison him.  [Superboy #153]
 An adult Lex Luthor terrorizes the great cities of the world (including London,
which is holding war games in case Hitler decides to attack) with a Superboy 
robot of his own creation, which the world believes is the real Superboy, or 
multiple Superboy robots.  The military forces of various nations destroy 
Superboy’s robots, but Luthor, posing as “Dr. Rothul”, offers his resource of 
refined Kryptonite to the American military--for a price.  Superboy sends his 
Clark Kent robot, disguised as an alien super-hero named Voltran, against 
Luthor’s Superboy robot, destroying it and exposing a cache of Kryptonite 
within it.  Luthor reveals himself, and Superboy, out of range of the 
Kryptonite, captures him. [Superboy #59] NOTE from Douglas Ethington: In 
Earth-1 continuity Kal-El and Lex Luthor were the same age.
 To ensure that Superboy does not interfere with the plan of Nazi world 
conquest, Adolf Hitler initiates a covert operation in Smallville.  Nazi 
spies mine the entire sewer system of Smallville, blow up the power station, 
and attempt to blackmail him into leaving Earth or facing the destruction of 
the whole town.  Superboy and a robot Jonathan Kent finally defuse the mines 
and capture the spies.  [Superboy #163]

NOTE from Commander Benson:

... There is one misattribution mentioned in one of those sites, and, in 
fact, is a common misconception regarding the Super-Sons.

That erroneous fact is crediting Denny O'Neil with the idea of determining
the Super-Sons to be probability-based creations of Superman's
super-ultivac computer, in order to reconcile them with the Earth-One DC

True, O'Neil did use this notion as the basis for his story "The Final
Secret of the Super-Sons", from World's Finest Comics # 263 (Jun.-Jul.,
1980). However, the idea was first advanced by Gerry Conway--in his story
"My Father . . . Superman", from Superman Family # 192 (Nov.-Dec., 1978).
In a scene showing Superman in his Fortress on page 1, panel 4 reveals the
Man of Steel's thoughts:

"Batman and I once used this computer probability simulator to project
what might have happened if Krypton had never exploded. And later, if we'd
married and had sons a few years ago . . . * That was an interesting
experiment, though a little bizarre."

The same panel contains a footnote:

"* At last, the true story behind the "Super-Sons" series in World's
Finest nos. 215, 216, 221, etc."

This was a rare--I say "rare" based on the number of times I've seen
Conway disregard established facts regarding characters in the DC
universe--instance where Conway cleverly employed an element from the
Silver-Age Superman.

You see, neither Conway nor O'Neil pulled out of their hats the idea of a
super-computer which displayed probable events based on scenarios fed to
it. It had been long established that Superman possessed such a computer
and it had been used recurringly during the Silver Age.

In the story "Superman's Other Life', from Superman # 132 (Oct., 1959),
the Man of Steel is entertaining the Batman and Robin in his Fortress of
Solitude, and he unveils for them his new "Super-Univac"--an advanced
simulation computer which, once fed all of the pertinent data and
background details, can determine the most probable outcome of a
hypothetical question fed to it, then presents this outcome in a visual
display. The plotline for "Superman's Other Life" was kicked off when
Superman feeds the Super-Univac the question "WHAT IF KRYPTON HAD NEVER

The simulations presented by the Super-Univac figured prominently in
several other DC stories in the early '60's--"The 'Superman' from Outer
Space" (Action Comics # 265 [Jun., 1960]) and "The Super-Life of Lois
Lane!" (Lois Lane # 47 [Feb., 1964]), among others.
