Jurassic Park is a 1990 science fiction novel written by Michael Crichton.
In 1993, Steven Spielberg adapted the book into the blockbuster film Jurassic Park, which won 3 Oscars, 19 other awards, and 15 nominations.
The narrative begins in August 1989 by slowly tying together a series of incidents involving strange animal attacks in Costa Rica and on Isla Nublar, the main setting for the story.
Alan Grant and his paleobotanist graduate student Ellie Sattler are abruptly whisked away by billionaire John Hammond—founder and chief executive officer of International Genetic Technologies, commonly known as InGen.
Upon arrival, the preserve is revealed to be Jurassic Park, a theme park showcasing cloned dinosaurs, which have been recreated using damaged DNA found in mosquitoes that fed upon dinosaur blood and were then trapped and preserved in amber.
Both are pessimistic, but Malcolm, having been consulted before the park's creation, is emphatic in his prediction that the park will collapse, as it is an unsustainable simple structure bluntly forced upon a complex system.
While touring the park with the children, Grant finds a Velociraptor eggshell, which seems to prove Malcolm's earlier assertion that the dinosaurs have been breeding against the geneticists' design. Malcolm suggests a flaw in their method of analyzing dinosaur populations, in that motion detectors were set to search only for the expected number of creatures in the park and not for any higher number. The park's controllers are reluctant to admit that the park has long been operating beyond their constraints.
n the midst of this, the chief programmer of Jurassic Park's controlling software, Dennis Nedry, attempts corporate espionage for Lewis Dodgson, a geneticist and agent of InGen's archrival, Biosyn. By activating a backdoor he wrote into the system, Nedry manages to shut down the park's security systems and quickly steal 15 frozen embryos, one of each of the park's fifteen species.
Without Nedry to reactivate the park's security, the electrified fences remain off, and dinosaurs begin to escape. The adult and juvenile Tyrannosaurus Rex attack the guests on tour, destroying the vehicles, killing public relations manager Ed Regis, and leaving Grant and the children lost in the park.
