In 1941, Wonder Woman burst onto the comic book scene — and into America’s burgeoning war efforts. As the superpowered Amazon joined WWII in the pages of DC Comics, the United States was testing the waters with its new international spy agency, the Office of Strategic Services. While the OSS would be disbanded mere months after World War II ended, the organization’s impact on Wonder Woman and the comics she called home is still felt today. And the connection runs deep: A mere year after she debuted, the OSS began an earnest search for “truth serum,” a questionable scientific pursuit that became a classic and recurring comic book device.
