as easily irritated. Novels In the first novel, Grant is described as "a barrel-chested, bearded man of forty". He had a wife who died years prior to the events of the novel. He has a strong affinity for children, especially those interested in dinosaurs. He is one of the world's most renowned paleontologists, partly specializing in hadrosaur and other duck-billed dinosaurs such as Maiasaura. Dr. Ellie Sattler is a graduate student and paleobotanist who is studying under Grant. Before the events of the novel, Grant was approached by Donald Gennaro, chief counsel for InGen, to provide information on the requirements for the care of infant dinosaurs, claiming it to be for a museum exhibit. Later, John Hammond's investors demand that he bring experts to his island, Isla Nublar, to certify the safety of a new theme park he is building there called Jurassic Park. Grant and Sattler agree to Hammond's invitation to tour the park, finding it difficult to turn down the request from a major financial donor. They are joined by Dr. Ian Malcolm, and are awestruck to learn that Hammond has cloned living dinosaurs. When the creatures escape, Grant becomes stranded in the park with Hammond's grandchildren, Lex and Tim. Throughout a large portion of the book, Grant and the children explore the park trying to find their way back to the rest of the group. Grant does not appear in Michael Crichton's sequel novel, The Lost World, but he is mentioned several times, including an instance stating that he is lecturing in Paris. Films Jurassic Park The film adaptation of Jurassic Park generally uses the same story and characters as the novel, though with some differences. For example, Grant is given an introverted personality and a dislike of children. The film also depicts him in a relationship with Ellie Sattler, as opposed to her being his graduate student. She wants to have a child, but Grant is resistant to the idea of starting a family. However, over the course of the film, he warms up to Hammond's grandchildren and protects them. Malcolm flirts with Sattler on several occasions, to the annoyance of Grant. Jurassic Park III In Jurassic Park III, Grant and Ellie are shown to have ended their relationship some time after the first film, although they remain close friends. Ellie has a minor role, and is now married to Mark, an employee of the U.S.
