Tim Murphy

Timothy "Tim" Murphy was the grandson of John Hammond who was invited to Jurassic Park because his parents were going through a divorce. In the film, some of his characteristics were swapped from the novel, with those of his sister Lex Murphy.

Jurassic Park (novel)
In the novel, Tim Murphy is shown to be an 11 year old who turns a blind eye on sports and instead shows interests in computers and dinosaurs. He is apparantly the least favorite Murphy child, as Lex is seen as bieng an avid sports fan (like her father). He is constantly bickering with his sister, but also tends to her while in the park. He is also a fan of Dr. Grant and respects his opinion throughout the book.

When John Arnold is killed and the computer terminal must be accessed, Tim uses his computer knowledge skills to turn the park's power on once again.
