Jurassic Park

Michael Crichton 

After its publication in 1990, Jurassic Park began a dinosaur craze that still extends into the realm of film and television today. The book’s well-loved characters are featured in a 1993 film starring Sam Neil, Jeff Goldblum, Laura Dern, and more. The film solidified the novel as one of the most influential fiction books of the 20th century.

Jurassic Park Character List

Dr. Alan Grant 

A paleontology professor at the University of Denver. He is someone who believes in hard work and getting out into the field. He and Dr. Ellie Sattler receive funding from the Hammond Foundation for a dig in Montana.  

He loves kids, struggles with technology, and is levelheaded. His composure and knowledge serve him and the other characters well when the dinosaurs escape, and they’re forced to contend with the many dangers the park presents. 

Grant deals with the children at the park, Lex and Tim, particularly well and spends much of the book protecting them. He’s drawn to their enthusiasm and Tim’s interest in learning more about paleontology. 

He is the main protagonist of the novel and one of the only characters to maintain a clear perspective and understanding of what’s going on in the park. 

John Hammond 

John Hammond is the head of the Hammond Foundation and the owner and operator of Jurassic Park. He also owns InGen and is known around the world as a dinosaur fanatic. He’s invested millions in a project aimed at successfully cloning dinosaurs and opening an amusement park/zoo/preserve so the wealthy can come and see them. 

His greed and ego get in the way of his understanding of what exactly it is he’s created and the dangers the park presents. He’s determined to open the park and have the public enjoy it no matter the costs. He’s particularly annoyed by Dr. Ian Malcom’s predictions that the park is doomed to fail spectacularly. 

As the novel progresses, it becomes clear that although Hammond expresses the right sentiment regarding everyday people visiting the island, he knows that only the world’s richest kids would ever step foot there. It’s steadily revealed that more than anything, Hammond is in it for the money. He meets a dramatic and ironic end within the park. 

Dr. Ian Malcom

Dr. Ian Malcom is another protagonist of the novel. He’s a mathematician who is highly skeptical of the island and Hammond’s intentions. He predicts nothing but failure and death for Jurassic Park and relates the animals to mathematical chaos theory. 

His character is outgoing, confident, and at times, arrogant. He gets on the nerves of all the other characters in the novel, especially Hammond, but he ends up being entirely correct in what he predicts for the park. 

Dr. Ellie Sattler

Dr. Ellie Sattler is another protagonist in Jurassic Park. She is a paleobotanist and works with Grant at his digs. She’s highly educated, thoughtful, and willing to get her hands dirty to help the group. 

In one key moment, she steps away from the tour to help understand why a stegosaur is sick. She also plays a key part in saving the group from the escaped velociraptors. 

Tim Murphy 

Tim Murphy is Hammond’s grandson. He’s talkative, loves dinosaurs and computers, and soon becomes obsessed with learning more from Alan Grant. Grant admires his enthusiasm and takes care of him and his sister, Lex. 

Lex Murphy 

Hammond’s granddaughter. She doesn’t get along great with her older brother but is very intelligent. She dislikes dinosaurs and loves baseball. 

Dennis Nedry 

Dennis Nedry is a villain in the novel. He’s a computer-system analyst at the park, overweight, and very hard to like. Nedry is smart but incredibly sloppy and disorganized. 

His irritation with Hammond and belief that he should be paid more than he is leads him to betray his employer and intentionally infect the park’s computer system. He attempts to smuggle dinosaur embryos out of the park and meets a gruesome fate for his effort. 

Donald Gennaro 

Donald Gennaro is the main lawyer for Hammond’s company, InGen. He wants the park to be safe for tis visitors but knows that he could make a fortune off it. He wants to open the park at first but, after seeing the disaster firsthand, is more than willing to help destroy it. It’s not worth the risk to people’s lives, he believes. 

Dr. Henry Wu 

Dr. Henry Wu is the park’s geneticist. He’s extremely intelligent but lacks common sense or complete knowledge of the instincts and capabilities of the creators he’s helping to create. He unknowingly engineers the dinosaurs with the ability to change sex. He refuses to acknowledge his mistake or admit that the dinosaurs are, in fact, breeding. 

Robert Muldoon

Robert Muldoon is Jurassic Park’s warden. He drinks a lot but can maintain order in the park, at first anyway. Muldoon’s background as a guide in Africa means that he has a great deal of on-the-job experience. He’s willing to risk his life to hunt down the dinosaurs and was one of the first to assert that having velociraptors in the park is a huge mistake. 

Ed Regis 

Ed Regis is a minor character and disgruntled InGen employee. He’s in charge of public relations for the park and is irritated that he has to watch over Hammond’s grandchildren while they visit. 

John Arnold 

John Arnold is the chief engineer. He finds himself in disagreement with Ian Malcolm on multiple occasions. He’s constantly nervous and unsure of himself, though. Arnold thinks he’s in control of the park, but, like other characters in the novel, he quickly finds out that that’s far from the truth. 

Dr. Harding

Dr. Harding is a vet at Jurassic Park. He used to work at the San Diego Zoo and is a minor character. 

Bob Morris 

Another minor character. He is an EPA investigator who is suspicious of what Hammond is up to on his island. 

Dr. Roberta Carter 

Dr. Roberta Carter works in Costa Rica and treats an injured InGen employee who supposedly got hurt in a construction accident. 


A paramedic working for Dr. Carter. 

Lewis Dodgson

A geneticist who works for Biosyn Corporation and who hires Nedry to smuggle dinosaur embryos out of the park.
