Wonder Woman assumed this alias very early during her tenure in the world outside of Paradise Island. In late 1941, Princess Diana met Diana Prince and noticed how similar they were in appearance. She paid her namesake a large amount of money to disappear, which enabled Diana Prince to alter her identity to fit Princess Diana's plans.
In September of 1942, Diana Prince returned to the United States and sought out Wonder Woman. She asked for her identity back so that she could find work to help out her inventor husband Daniel White and their infant child. Wonder Woman agreed, but soon after, Nazi spies kidnapped Diana and forced her to give them one of her husband's inventions. Wonder Woman rescued Dan White and apprehended the spies. When the invention proved successful, Diana Prince relinquished her legal name and began referring to herself by her married name Diana White. After this, Wonder Woman began using the Diana Prince identity again.
- This version of Diana Prince, including all history and corresponding appearances, was erased from existence following the collapse of the original Multiverse in the 1985–86 Crisis on Infinite Earths limited series. Even though versions of the character may have since appeared, this information does not apply to those versions.
- Two of the appearances of the "Earth-One" Diana Prince (Wonder Woman #162 and Wonder Woman #167) were retconned to being on Earth-Forty and Earth-Thirty-Two respectively, making her only Earth-Two appearance DC Special Series #19. Since Earth-Forty is a distorted Earth-Two with regard to Wonder Woman, it is assumed the Diana Prince of Wonder Woman #162 and this one had effectively identical histories.
- Princess Diana's identity-adopting encounter with Miss Prince took place well before the June 1942 cover date of Sensation Comics #1. By early December of 1941, as shown in Justice League of America #193, Wonder Woman was already a well-established and famous super-heroine.
