Flight coordinator McQueen was the most intelligent human crewmember aboard the JMC mining spaceship Red Dwarf, with an I.Q. of 172. McQueen was "superlative" in the field of mathematics.

McQueen died in the radiation leak which killed almost all of the crew, except Dave Lister, who was in stasis at the time.

Three million years later, McQueen was revived, or at least his mathematical knowledge, in an illegal Mind Patch with the hologram Rimmer, as well as that of Science Officer Buchan's scientific knowledge. The Mind Patch was performed by Kryten to help Rimmer become intelligent enough to join the Enlightenment.

Although the plan initially worked, Rimmer's mind eventually rejected the two vastly superior intellects. ("Holoship", Series V)
