Irving Bailiff is the senior-most Macrodata Refiner at Lumon Industries. He has a no-nonsense demeanor and takes the Kier philosophy very seriously. Irving is known to abide by Lumon rules strictly and often cautions his colleagues when they are in violation of them. He comes from a very regimented background.
At work, he has a reputation for falling asleep at his desk. He has terrifying dreams about his cubicle being overtaken by thick black goo. Irving seems to be punished less harshly than other Innies, likely because he is such a diligent worker and commits infractions so infrequently.
At home, he has an obsessive impulse to paint the hallway leading to the Testing Floor elevator, though his Outie can have no memory of that location. He paints with great gusto, slathering thick acrylic paint with a pallet knife while listening to hard rock. He may always listen to The Ace of Spades when he paints, as that song seeps into the black goo dreams his Innie experiences.
Irving’s father was in the US Navy. Irving has some of his medals displayed in his home. Irving himself also appears to have been in a branch of the military.
Irving’s Innie mentions that he has worked at Macrodata Refinement (and possibly Lumon) for three years, making him the longest-tenured employee in his department. There are theories that he has actually worked for Lumon for much longer, but his memory has been reset in some way on the Testing Floor.
According to the facts about his Outie shared in his wellness session in episode two, Irving likes the sound of radar. He is fond of movies and has a machine that can play them. He is also fond of records. Irving paints the same image of the long dark hallway leading to the Testing Floor over and over again. He is a powerful swimmer and popular dancer, and is skilled at kissing and lovemaking.
