Colonel John Jameson, son of newspaper mogul J. Jonah Jameson, was one of the youngest applicants to ever be accepted into NASA's astronaut program. During his first mission, in which he was to orbit Earth, the Forward Guidance Package on Jameson's capsule broke off in space, which caused the craft to spin out of control and plummet back down toward earth. The fledgling adventurer, Spider-Man, who had just begun his career weeks earlier, managed to rescue Jameson by getting a replacement guidance module and attaching it to the falling capsule. John was then able to land the craft safely. This incident, which Jameson's father construed as a publicity stunt to upstage his son's accomplishment, provoked the first of the elder Jameson's editorial denouncements of Spider-Man.
Sometime later, Jameson was selected to go on a secret mission to the moon, the reason for which is still classified information. While collecting lunar rock samples, he came across a glittering red gemstone, unlike anything else he had seen there. At the successful completion of the mission, Jameson felt a strange compulsion to possess the unique gemstone, and with the assistance of a colleague, Jameson had it recovered from quarantine and made into a pendant. Jameson was wearing it around his throat on the first night of a full moon when lunar luminescence reacted with the pendant, causing him to transform into a wolf-like humanoid creature, to be called Man-Wolf!
