Rear Admiral Francis "Frank" Henderson was born on the Inner Colony of Hawkins on the 5th of April 2497 to Jeremy and Kira Henderson. His parents were both officers of the UNSC Navy, with his father being a Captain of the UNSC Last Call Marathon cruiser and his mother the Executive Officer of the UNSC Twilit Dawn. This gave Frank the eligibility to be taught at CAMS, where he was trained and graduated with full honours in 2516, before joining the UNSC Navy as an enlisted Non-Commissioned Officer on the UNSC Steele.
