Tessier-Ashpool is a fictional family appearing in William Gibson's Sprawl trilogy novels. The family owns Freeside, a space station shaped like a spindle Bernal sphere constructed in high orbit. The family resides in the Villa Straylight, which occupies one end of the spindle.
The family is organized and run as a corporation, Tessier-Ashpool S.A.. Family members are kept under cryogenic stasis and thawed out periodically so that governance of the family is cycled between members. According to "orbital law" they are legally dead while cryogenically preserved.
The Tessier-Ashpool family owns the mainframe to which one of their two artificial intelligences, Wintermute, is attached. As the computer hardware is located in Bern, Switzerland its resident AI thereby has limited Swiss citizenship "under their equivalent of the Act of '53". The other AI, Neuromancer, is housed within another family-owned mainframe located in Rio de Janeiro, Brazil.
