The Golden Age Wonder Woman had strength that was comparable to the Golden Age Superman. Wonder Woman was capable of bench pressing 15,000 pounds even before she had received her bracelets, and later hoisted a 50,000 pound boulder above her head to inspire Amazons facing the test. Even when her super strength was temporarily nullified, she still had enough mortal strength of an Amazon to break down a prison door to save Steve Trevor. In one of her earliest appearances, she is shown running easily at 60 mph (97 km/h), and later jumps from a building[clarification needed] and lands on the balls of her feet.
When Marston died in 1947 Robert Kanigher took over and Diana became less of a feminist character but during this time, her abilities expanded as she wore earrings that provided her with the air she needed when she was in outer space and she had an invisible plane. Extra additions included a tiara which could cut through almost anything and acted as a boomerang and her bracelets now had two way radios.
Wonder Woman was created by the American psychologist and writer William Moulton Marston (pen name: Charles Moulton), and artist Harry G. Peter. Marston's wife, Elizabeth, and their life partner, Olive Byrne, are credited as being his inspiration for the character's appearance. Marston's comics featured his ideas on DISC theory, and the character drew a great deal of inspiration from early feminists, and especially from birth control pioneer Margaret Sanger; in particular, her piece "Woman and the New Race".
This new era of the comic book was influenced by the British television series The Avengers, with Wonder Woman in the role of Emma Peel. With Diana Prince running a boutique, fighting crime, and acting in concert with private detective allies Tim Trench and Jonny Double, the character resembled the Golden Age Black Canary. Soon after the launch of the "new" Wonder Woman, the editors severed all connections to her old life, most notably by killing Steve Trevor.

Thus although by the modern depiction her accomplishments at the time seem ordinary, in that era they were more so. Diana Prince was originally an army nurse, but quickly attained the rank of lieutenant in Army Intelligence. This was partially a creative convenience so that she could be close to both Steve Trevor and received information which she needed to pursue her superheroics. In the real world though, this role in Army intelligence, even as the secretary to General Darnell, was still a rare position for a woman to hold in society. At this time as well, the character had her only real sidekicks in her history in the form of Etta Candy and the Holliday Girls. These characters gave the Wonder Woman a degree more of levity while also allowing the writers to focus on some issues which were more related to women. When Marston left the character, the strong driving force of the character to act as a strong moral guide and role model for female readers left as well and the character became more sensitive to the forces driving the industry as whole. Thus Wonder Woman changed somewhat to a more stereotypical woman. Her main interest was not always fighting crime, but for a time it became all in the interest of keeping Steve Trevor happy and interested in her for marriage. Also the backup stories featuring the Wonder Women of History were slowly phased out and replaced with features on marriage customs from around the world and trivial facts on random household objects.
