The original Iron Man title explored Cold War themes, as did other Stan Lee projects in the early years of Marvel Comics. Where The Fantastic Four and The Incredible Hulk respectively focused on American domestic and government responses to the Communist threat, Iron Man explored industry's role in the struggle. Tony Stark's real-life model, Howard Hughes, was a significant defense contractor who developed new weapons technologies. Hughes was an icon both of American individualism and of the burdens of fame. Historian Robert Genter, in The Journal of Popular Culture, writes that Tony Stark specifically presents an idealized portrait of the American inventor. Where earlier decades had seen important technological innovations come from famous individuals (e.g., Nikola Tesla, Thomas Edison, Alexander Graham Bell, the Wright brothers), the 1960s saw new technologies (including weapons) being developed mainly by the research teams of corporations. As a result, little room remained for the inventor who wanted credit for, and creative and economic control over, his/her own creations. Issues of entrepreneurial autonomy, government supervision of research, and ultimate loyalty figured prominently in early Iron Man stories -- the same issues affecting American scientists and engineers of that era. Tony Stark, writes Genter, is an inventor who finds motive in his emasculation as an autonomous creative individual. This blow is symbolized by his chest wound, inflicted at the moment he is forced to invent things for the purposes of others, instead of just himself. To Genter, Stark's transformation into Iron Man represents Stark's effort to reclaim his autonomy, and thus his manhood. The character's pursuit of women in bed or in battle, writes Genter, represents another aspect of this effort. The pattern finds parallels in other works of 1960s popular fiction by authors such as "Ian Fleming (creator of James Bond), Mickey Spillane (Mike Hammer), and Norman Mailer, who made unregulated sexuality a form of authenticity."
