Lex Murphy

Alexis "Lex" Murphy was the thirteen-year-old granddaughter of John Hammond and older sister of Tim Murphy. She and her younger brother came to Jurassic Park to visit their grandfather, and also to go on the initial tour of the park, since Hammond seemed to be specifically aiming the park at children. A bit of a computer nerd, and a self-described "hacker," Lex was amazed by the level of technology displayed in the Explorer tour car's onboard CD-rom system. During the tour, she disliked the fact the Tyrannosaurus was fed live goats, but was nonetheless disappointed when the dinosaur did not show itself at first.

Lex was very nearly traumatized by the Tyrannosaur's attack on the tour vehicle she and her brother were in when Donald Gennaro, who had been riding with them, abandoned them in panic moments before the attack came. Because if this, she at first refused to leave Dr. Alan Grant's side following the ordeal. Eventually though, she calmed down and became her old self again. After arriving at the visitor's center and narrowly escaping death at the claws of Velociraptors in the kitchen, she ran to the control room with Grant, Dr. Ellie Sattler and Tim.

There, she used her computer skills on Dennis Nedry's computer, and managed to fix what he had done by rebooting the phones and door locks, allowing the survivors to call for help. She survived the ordeal.

Like her brother, she showed up again for a brief renunion with Dr. Ian Malcolm at Hammond's mansion in San Diego, where they'd come to cheer their grandfather up following his overthrow as InGen's president by their cousin Peter Ludlow.
