Truly Trivial: What was the original written formulation for E=mc2?

The old trivia geek is bogged down with day job wonkery, so I'm reprinting this old-school Geek Trivia from my TechRepublic days, "Eye for an Einstein." I quote from it thusly:

Einstein proved that even apart from movement, all objects that possess mass also possess energy. You can find out exactly how much energy with the simple calculation of mass multiplied by the square of the speed of light, E=mc2.
The crazy thing is, you won’t find this famous equation in any of Einstein’s papers published before, during, or after 1905. That’s because Einstein never wrote his most famous equation in its most famous form.
Instead, he earned his scientific accolades expressing energy-mass equivalence very differently.
WHAT WAS THE ORIGINAL FORMULATION OF E=mc2 AS WRITTEN BY EINSTEIN?
