Autumn senior was a high-ranking Enclave scientist and the father of Augustus Autumn.
After the destruction of Control station Enclave, Autumn received orders from the President, telling him and all surviving Enclave troops to relocate to the Raven Rock military base on the opposite end of the country. He obeyed the order, gathered his troops and their equipment, and led his men through the post-nuclear United States. Upon the Enclave's arrival in the Capital Wasteland, he was the only one privy to the fact that John Henry Eden is actually a ZAX unit that has achieved self awareness. Prior to his death, he passed that knowledge onto his son, Augustus Autumn, who would later become the leader of the Enclave's military.
- Fallout 3 Official Game Guide Game of the Year Edition p.66: "Colonel Augustus Autumn
Autumn grew up on an oil rig off the California coast (the base of operations for the Enclave, the secretive contingent of the United States government that survived after the apocalypse). His father was the high-ranking Enclave scientist on orders from the president to move all high-ranking officials to the only other secure Enclave location with a functioning ZAX super-computer, Raven Rock. Colonel Autumn has proven to be far less subservient than his scientist father, often openly disagreeing with the president's decisions."
