Storyline
Fictional biography
Galactic Empire First Minister and psychohistorian Hari Seldon was born in the 10th month of the 11,988th year of the Galactic Era (GE) (-79 Foundation Era (FE)) and died 12,069 GE (1 FE).
[According to the '' Encyclopedia Galactica'' (Asimov's fictitious encyclopedia often cited in his future history novels), "It is thought that Seldon's birthdate, which some consider doubtful, may have been adjusted to match that of Cleon's" the last Galactic Emperor of the Entun Dynasty (''Prelude to Foundation'', p. 3).][In Asimov's saga, the Galactic Era begins when the Galactic Empire is founded at an unknown date roughly 11,000 years in the future: The timeline can be deduced from some hints Asimov dropped in his other science fiction works, including the ''Robot'' and ''Empire'' series.]

). Helicon is said to be "less notable for its mathematics, and more for its martial arts" (''Prelude to Foundation''). Seldon is awarded a Ph.D. in mathematics for his work on turbulence at the University of Helicon.
There he becomes an assistant professor specializing in the mathematical analysis of social structures.
Seldon is the subject of a biography by
Gaal Dornick. Seldon is Emperor
Cleon I's second and last First Minister, the first being
Eto Demerzel/
R. Daneel Olivaw. He is deposed as First Minister after Cleon I's assassination.
''Foundation''
Using psychohistory, Seldon mathematically determines what he calls ''The Seldon Plan''—a plan to determine the right time and place to set up a new society, one that would replace the collapsing
Galactic Empire by sheer force of social pressure, but over only a thousand-year time span, rather than the ten-to-thirty-thousand-year time span that would normally have been required, and thus reduce the human suffering from living in a time of barbarism. The Foundation is placed on
Terminus, a remote and resource-poor planet entirely populated by scientists and their families. The planet—or so Seldon claimed—was originally occupied to create the ''
Encyclopedia Galactica'', a vast compilation of the knowledge of a dying galactic empire. In reality, Terminus had a much larger role in his Plan, which he had to conceal from its inhabitants at first.
''Prelude to Foundation''
Seldon visits Trantor to attend the Decennial Mathematics Convention. He presents a paper which indicates that one could theoretically predict the Galactic Empire's future. He is able to show that Galactic society can be represented in a simulation simpler than itself (in a finite number of iterations before the onset of chaotic noise smears discerning sets of events).
He does so using a technique invented that past century. At first, Seldon has no idea how this could be done in practice, and he is fairly confident that no one could actually fulfill the possibility. Shortly after his presentation, he becomes a lightning rod for political forces who want to use psychohistory for their own purposes. The rest of the novel tells of his flight, which lasts for approximately a year and which takes him through the complex and variegated world of Trantor. During his flight to escape the various political factions, he discovers how psychohistory can be made a practical science. It is in this novel that he meets his future wife

, as was the case with the original trilogy. They take place at intervals a decade or more apart, and tell the story of Hari's life, starting about ten years after ''
Prelude'' and ending with his death. The stories contrast his increasingly successful professional life with his increasingly unsuccessful personal life.
Seldon becomes involved in politics when
Eto Demerzel becomes a target for a smear campaign conducted by Laskin Joranum. He eventually takes Demerzel's place as First Minister, despite his reluctance to divide his attention between government and the development of Psychohistory. His career comes to an end when Cleon I is assassinated by his gardener (a random event Seldon could not have predicted) and the seizure of power by a military junta. Seldon eventually causes the fall of the junta by dropping subtle false hints about what Psychohistory foresees, leading to the Junta making unpopular decisions. However, an agent of the Junta inside Seldon's team, having deduced that Dors is a robot, builds a device that ultimately kills her, leaving Seldon heartbroken. Years later, Seldon discovers that his granddaughter Wanda has telepathic abilities and begins searching for others like her but fails. Raych eventually decides to move his family to the planet Santanni, but Wanda chooses to remain with her elderly grandfather. However, just after they arrive a rebellion breaks out on the planet and Raych is killed in the fighting. His wife and child are lost when their ship disappears. Seldon eventually finds Stettin Palver, another telepath who becomes Wanda's husband and the pair are eventually instrumental in creating the Second Foundation.
Seldon mentions two indigenous species of Helicon: the lamec and the greti. The first is a hardworking animal, while the latter is dangerous as indicated by the native Helicon saying "If you ride a greti, you find you can't get off; for then it will eat you." The saying is similar to the age-old Chinese proverb "He who rides the tiger finds it difficult to dismount", and the words ''lamec'' and ''greti'' are anagrams of ''camel'' and ''tiger'', respectively.
In his old age, he gains the nickname ''Raven'' for his dire predictions of the future.
