Dr. Gerald "Gerry" Harding is Jurassic Park's chief veterinarian. Formerly a bird expert for a major zoo, he accepted the job because he wanted to become famous for being the first person to write a textbook on the care of dinosaurs. When the group first encounters him, he is looking after a sick Triceratops. With the help of Ellie Sattler, he finds the source of the animal's sickness and is able to treat it. Being the only doctor on the island, he is the one who treats Malcolm after he is attacked by the Tyrannosaurus. He is attacked by a Velociraptor during the assault on the visitor's center, but ultimately survives his time on the island. It is revealed that Sarah Harding is Gerry's daughter.
His torso is the same as the desert outfit from Indiana Jones, but only in green.
