Jean Louis Roget was the father of Celeste Roget and an engineer who once designed a revolutionary, and ultimately rejected, plan for a transatlantic tunnel. He was not a religious man, but after the events of World War II, he often spoke of the horrors of nuclear weaponry. He was one of those who disappeared to Rapture in 1946 during The Vanishing. Little is known about his time spent there, other than that he created some Ryanist propaganda pamphlets for The Bacchanal Press.
