Elihas Starr was a government scientist who was caught and jailed after smuggling blueprints out of work, presumably to sell on the black market. The media dubbed him "Egghead," and he was soon contacted and freed by a high-placed crime lord, who gave him the charge of proving his worth by defeating the original Ant-Man. Although using his technological expertise, Egghead failed and narrowly avoided capture.
Time and again, he would try to defeat Hank Pym, such as trying to use Ant-Man’s new partner, the Wasp, as bait, or trying to trick Ant-Man into fighting against Spider-Man. Egghead regarded Pym as his arch-nemesis and grew desperate to prove Pym’s genius was inferior to his own.
Giving up on pure revenge, Egghead tried to form a short-lived alliance with the Mad Thinker and the Puppet Master. They hoped to use an orbiting laser death ray to extort money from the United States but were defeated by the Avengers when Barney Barton, brother of Hawkeye (then, Goliath), tipped off the heroes. Tragically, Barney died in the ensuing battle. Later, Egghead would use the Swordsman (Jacques Duquesne) to capture Goliath, thinking him to be Hank Pym, but Hawkeye (Clint Barton) as Goliath soon defeated both criminals, avenging his brother at the same time. -ComicVine
