Arthur Quandt is a member of Majestic-12.
Arthur Quandt was born to a wealthy family that owned a steel trading empire. At an unknown point, Quandt become the head of the empire, and later was invited to join Majestic-12, a group of twelve of some of the richest men in the world.
When Majestic-12 decided to enhance their overall fortunes, they began planning to initiate a new Cold War, which their individuals businesses would benefit from and improve their wealth. Through Jonathon Killian's Axon Corp contracts with the U.S. military, they discovered a pair of top secret American projects known as Kormoran and Chameleon, which involved disguised battle tankers and clone missiles respectively. By taking over both these projects, M-12 could make several western countries believe they had been hit by terrorist missiles.
In the course of their planning, M-12 discovered that a few individuals could upset their plans due to certain skills or knowledge that they possessed, and so they decided to start a bounty hunt to keep them from doing so. It was soon decided that Killian's Forteresse de Valois castle would be used as the verification point where the heads of the targets would be brought for assessing by Monsieur Delacroix, whom M-12 had worked with in the past.
Among the fifteen targets was Shane Schofield, a U.S. Marine with a reputation for succeeding against the odds. Unsettled by this, Quandt and M-12 decided that they would arrange a sham mission as an ambush to increase the chances of him being eliminated.
Shortly after the hunt began, Quandt and the other members of Majestic-12 engaged in a telconference to discuss the current happenings of their plan.
Ultimately, however, Schofield managed to disarm the Chameleon missiles and arranged for the U.S. government to bring down the Kormoran tankers, foiling Majestic-12's plan.
Soon afterwards, Quandt was murdered at his Aspen lodge, having been targeted for assasination by the U.S. government because of M-12's plan, and his mistress was also murdered to increase the illusion that someone else killed them both. In the aftermath of his murder, Quandt's heir inherrited his empire and wealth.
