Following her debut in All Star Comics #8 Wonder Woman appeared in her first own series headlining a new monthly title called Sensation Comics. The title also had around four to five other stories each month, featuring various other characters though not all necessarily super heroes.
Wonder Woman flies the wounded Trevor back to America in her invisible plane and deposits him at the Walter Reed Army Hospital. She wanders aimlessly through the streets of Washington D.C., familiarising herself with this strange new world of men. In the process she foils a bank robbery and meets an unscrupulous promoter named Al Kane.
She then heads back to the hospital to try and find some way to remain close to Steve and comes across a bespectacled nurse crying on the steps of the entrance way. The nurse tells Wonder Woman that her fiance has got a job in South America but he cannot afford to send for her yet to join him. The Amazon Princess thinks for a moment and removing the nurse’s glasses, remarks how similar in appearance the two women are. She offers to give the nurse the money she needs by buying her identification and credentials from her. That way they can both be with the man they love! The nurse agrees and reveals her name to coincidentally be Diana too – “Diana Prince”.
And so, donning glasses and uniform in her new guise as nurse Diana Prince, Wonder Woman adopts a secret identity that will serve her well for many years to come!
