Dors Venabili

In Isaac Asimov's Foundation Series, Dors Venabili is a good friend, protector and later wife of Hari Seldon, the primary character of Prelude to Foundation and Forward the Foundation. At face value, Dors is an attractive woman, two years younger than Seldon. She tells Seldon that she is a historian from Cinna, and, before her involvement in The Flight, Dors taught history classes at Streeling University on Trantor.

Dors is probably one of the strongest and most developed female characters of the Foundation Series. She has been assigned the task of protecting Hari Seldon by Chetter Hummin (one of several aliases used by R. Daneel Olivaw) who takes an initial interest in Hari Seldon's psychohistory research. Over the course of Prelude to Foundation and Forward the Foundation she shows an obsessive concern for his safety and earns the nickname "The Tiger Woman" for the ferocity with which she is willing to defend him, and her accuracy, reflexes, and skill (all thought to be superhuman to the point of feline). Despite that, throughout her lifetime protecting Seldon, she was always reluctant to harm opponents in the course of protecting her husband. This is a result of her being bound by the Laws of Robotics.

Toward the end of Prelude to Foundation, Hari reveals his suspicion that Dors is a gynoid working with R. Daneel Olivaw on his mission to protect mankind. (Clues that reveal Dors' true nature include her learning to master a weapon skillfully and immediately after watching a gangster use it just once.) This suspicion has no apparent effect on Hari's love for Dors. In fact, Seldon only finally admits to himself that his wife is a robot at the time of her death, and even then is unperturbed by that fact. Dors dies in Seldon's arms after being his spouse for 28 years, apparently as a result of both the EM damage inflicted during the attempt on her life by a traitor in Seldon's ranks, Tamwile Elar, and a violation of the First Law of Robotics as Dors kills Elar in defense of the Psychohistorical Project, thus essentially choosing to follow the Zeroth Law and suffering a fate similar to that of R. Giskard Reventlov. At the point of Seldon's death, he thinks of his protectress and wife in love, not in anger over her deception.

Together they raise Raych, whom they encounter as a 12 year old boy while in the Dahl sector of Trantor.

Dors reappears in The Second Foundation Trilogy after her apparent death, having been repaired by Daneel. She is originally assigned new duties, but has difficulty adapting to them. Having been built for the specific purpose of caring for Hari Seldon, her absence from his life and her knowledge of his impending death give her new perspective on Daneel's orders. Eventually, she leaves his service entirely, and it is implied that she takes up with the robot Lodovik Trema, but only after one final visit to her husband, whose last recorded word was her name.
