Captain America

Steve Rogers was born July 4, 1922, to poor Irish immigrant parents, Sarah and Joseph Rogers[1], and grew up a frail youth during the Great Depression in America. Rogers' father died when he was a child and his mother died from pneumonia later, when he was in his late teens[2].

Becoming America's Super-SoldierHorrified by newsreel footage of Nazis ransacking Europe and atrocities in Asia that the Empire of Japan committed in China and Korea, Rogers tried to enlist in the Army, that rejected him as 4-F because of his frailty and sickness. Overhearing the boy's earnest plea to fight for his country, General Chester Phillips, of the US Army, offered Rogers the opportunity to take part in a top-secret performance-enhancing experiment called Operation Rebirth. Rogers agreed and was taken to a secret laboratory in Washington, D.C., where he was introduced to Doctor Abraham Erskine (code named Professor Joseph Reinstein), the creator of the Super-Soldier Serum[3].

After weeks of tests, Rogers was at last administered the Super-Soldier Serum. Given part of the compound intravenously and another part orally, Rogers was then bombarded by vita-rays, a special combination of exotic (in 1941) wavelengths of radiation designed to accelerate and stabilize the serum's effect on his body. Steve Rogers emerged from the vita-ray chamber with a body perfect human body. A Nazi spy, who observed the experiment, murdered Dr. Erskine mere minutes after its conclusion. Dr. Erskine died without fully committing the Super-Soldier formula to paper, leaving Rogers the sole beneficiary of his genius.

Rogers was then put through an intensive physical and tactical training program, that taught him gymnastics, hand-to-hand combat from Colonel Rex Applegate and William Essart Fairbairn, and military strategy. Three months later, he was given his first assignment: to stop the Nazi agent called the Red Skull. To help him become a symbolic counterpart to the Red Skull, Rogers was given the red, white, and blue costume of Captain America.[4] Rogers was also given the cover identity of a clumsy infantry private at Camp Lehigh.

After successfully becoming Captain America, Rogers was later submitted to an experimental mind-conditioning program that conditioned his mind to accept false information in the chance he was captured by the enemy and forced to reveal classified information. As part of the conditioning, Rogers believed his real name to be Grant Rogers, that he had a brother, and that due to his parents being diplomats, he had a casual upper class appointment to the Army and Captain America position. It would not be until far later in life that Rogers would recall the conditioning and his true history[5].

Rogers was originally issued a traditionally shaped "kite" shield made of mundane steel, as well as a sidearm. Cap's original helmet served as a mask and was separate from the rest of his costume. This proved a problem as in one early outing it was nearly knocked from his face via the hard wing emblems, almost revealing his identity to an attending newspaper reporter with camera[2]. Adding a protective neck-plating hood to his costume, rather than his separate mask, solved this problem and afforded Rogers more protection. President F.D. Roosevelt later presented Rogers with his now-legendary disc-shaped shield. Discovering that its excellent aerodynamic properties made it an effective offensive weapon, Rogers abandoned his sidearm.
