Tannen Manor in 1971B.
Tannen Manor was a home located in Hill Valley, California in the alternate timeline where an elderly Biff Tannen traveled from 2015 to 1955 with a Grays Sports Almanac to make himself rich.
History[]
Biff had the plans for the manor drafted in 1971, but the zoning commission deemed that it was too large. Biff barged into the city council meeting, and demanded a vote to get his plans approved. However, Stanford S. Strickland objected, as the vote had to be unanimous in order for plans to carried out. Biff tried to bribe Strickland by telling him that he would build a new gym for Hill Valley High School and call it the "Gertrude Tannen Memorial Gym". However, Strickland refused, saying he could not be bought off and "no Tannen ever amounted to anything in Hill Valley" and that their family name was unworthy of being immortalized on an educational institution. Biff later sent a box of cigars to Strickland at his office at the high school, with a note that made it seem they were a gift from someone who was happy that he stood up to Tannen. When Strickland lit one, it turned out to be a novelty exploding cigar, which exploded and set light to a pile of papers on his desk. When Mr. Strickland tried to put the fire out with the fire extinguisher, the fire grew out of control as Biff's gang had discreetly replaced the extinguisher fluid with flammable accelerant.
Biff sent a photograph of Strickland lighting the cigar in his office, which led to an investigation. Strickland was forced to step down as principal and as a member of the city council while the investigation was in process. With Strickland out of the way, Biff's mansion plans were approved.
The mansion was complete by 1972, when Biff held a ceremony for "Mother of the Year" there, declaring Lorraine Baines McFly the recipient of the award. However the ceremony was a two-fold ruse, the first being to improve the image of BiffCo by showing Biff as a generous sponsor and good citizen, and the second being Lorraine to come to his new mansion, and he also invited her entire family to watch her receive this honor. She was disgusted, but her parents, Sam and Stella were overwhelmed by his wealth. Sam wondered if Lorraine would have married Biff if he hit him with his car instead of "that other kid". While Sam was joking, both he and Stella had been seriously worried about Lorraine having three kids to support. The 1970s had had a poorer economy as opposed to the comparative prosperity they enjoyed when they were young parents, and their son-in-law George seemed to be in a dead-end job at the newspaper. Biff could have provided Lorraine with a life they could only dream of and ensure their grandchildren never went to bed hungry.
Later that year, Biff's second wife, Jayne Mansfield, discovered a fallout shelter beneath the mansion. Instead of being equipped with civil defense items, it was a shrine to Lorraine, full of portraits and sculptures of her. While Jayne Tannen could not find proof of cheating on her, this secret room showed signs of erotomania and possible stalking of Lorraine. Disgusted, she left the manor and initiated divorce proceedings against her husband, with the Lorriane shrine as evidence prima facie of adultery.
In 1973, Biff shot George McFly in an alley and had a member of the Hill Valley Police Department, which he controlled, cover it up by pinning George's murder on Red the Bum, by planting George's wallet on him. With George gone, Biff was able to convince Lorraine to marry him, in order to help her family, who were all in financial trouble because of Biff's dealings through BiffCo.
After the marriage, Lorraine moved into the mansion with her children, Marty, Dave, and Linda. Dave was disgusted with his new stepfather, and in 1981 he joined the Hill Valley Civic Committee to try to stop BiffCo. He knew that Biff kept a safe in the mansion, so Terry planned to break into it while Biff and his family were at dinner. However, Biff stayed behind and caught Terry in the act. He had the police officers that he controlled beat him to death, and then had them run Dave out of town. With Dave gone, Lorraine feared for the safety of her other children. She sent Marty and Linda to boarding schools, telling her husband she wanted the best education possible for her children. Biff agreed with this decision and paid the tuitions of Marty and Linda, arguably seeing it as a chance to be rid of all three of his stepchildren. It is unknown which boarding school Linda attended, but it is known after graduation she owned multiple credit cards and had gotten herself in financial trouble with a bank. Marty did not seem to adjust to such an academic environment, having been expelled from at least one boarding school. He was then sent to Switzerland, which had a stellar reputation for education.
After the construction of Biff Tannen's Pleasure Paradise Casino & Hotel, Biff and Lorraine moved there to live in the penthouse suite, and Biff moved his safe there as well.
