François McGillicuddy was a Mesan citizen, entrepreneur and politician.
He was the grandson of Genevieve McGillicuddy, a member of Mesan high society. In the 1920s PD, he served as a senior board member of Atkinson, McGillicuddy & Shivaprakash, a major transstellar investment firm with branches in many of the Solarian League's core systems. He also served as Mesa's Director of Security.
He was not a member -- and not aware of the existence -- of the Mesan Alignment. When the "Audubon Ballroom terrorist attacks" of 1922 PD began, he was heavily in favor of a swift and brutal response against the seccy population, unaware that the attacks were actually part of Operation Houdini.
