Allistair Tenpenny

 is the owner of Tenpenny Tower in 2277.

Background
An 80-year-old Englishman turned American entrepreneur, the man who discovered the tower saw it as an opportunity to provide residents with a standard of living enjoyed by the affluent in the days before the nuclear Armageddon. A rich eccentric who's bored with life and looking for new challenges, he enjoys sniping at Wasteland creatures, ghouls, and the occasional visitor from his suite atop Tenpenny Tower. Nothing indicates that he ever had a wife or was with children.

Tenpenny spends most of his days alone, save for the company of Mister Burke, along with occasional sex visits from Susan Lancaster. Mei Wong, a woman in Rivet City, used to be Tenpenny's slave.

Daily schedule

 * Tenpenny is a recluse, never leaving his penthouse suite, although it is mentioned he has a seat in Margaret Primrose's cafe.
 * He carries a sniper rifle which he uses to shoot at things in the wastes during what he calls "Wasteland Safari."
 * He sits on his balcony, enjoying the view from his tower, bothered only by a certain "eyesore" in the horizon. He also seems to enjoy drinking whiskey, smoking tobacco and playing chess, all indicated by the nearby whiskey/shotglass, cigarette pack/ashtray and chessboard.
 * He orders his daily meals from Margaret Primrose, ordering a "Iguana bit sandwich, no salt, with a peeled pear on the side". Allistair also has a private seat in the corner of Margaret's cafe, as explained when you first meet Margaret.

Quests

 * The Power of the Atom: The player can stand on Tenpenny's balcony with Allistair and Mister Burke and together witness the destruction of Megaton in a nuclear explosion. If you choose to blow up Megaton for Tenpenny and Burke, Tenpenny will give you a suite in the tower.
 * You Gotta Shoot 'Em In The Head: Mister Crowley wants to hire the player to kill Tenpenny. If confronted, Tenpenny will make a counter-offer, hiring the player to kill Crowley.
 * Tenpenny Tower: The player can convince Tenpenny to give his permission for the ghouls to move in. If you allow Ghouls to move in, Roy Phillips and Tenpenny will have a "disagreement" and Tenpenny will have an "accident", which results in Tenpenny's body being stuffed in a storage closet.
 * Slave Hunt : Tenpenny is the former owner of Mei Wong and is mentioned in this unmarked quest.

Behind the scenes

 * Tenpenny brings Howard Hughes to mind.
 * Both men are wealthy recluses.
 * Tenpenny's suite is littered with milk bottles; Hughes also amassed milk bottles in his rooms.
 * There is a row of empty Nuka-Cola bottles next to Tenpenny's door; Hughes urinated in his emptied milk bottles and lined them up near the door.
 * Allistair's and his nemesis, Mr. Crowley's last names are most likely a reference to the famed British occultist, Aleister Crowley
