Dr. Gerry Harding was the veterinarian at Jurassic Park, Dr. Gerry Harding made sure all the dinosaurs remained healthy and when one became ill, he was on hand to treat it. He was first seen treating a sick Triceratops. With paleobotanist Dr. Ellie Sattler's help, he was able to diagnose the animal's condition. Apparantly, it had eaten a poisonous plant called the West Indian Lilac and become ill, despite his previous belief that the dinosaurs didn't eat them. Later, Harding drove Ellie back to the visitor's center in his gas-powered Jeep. He left the island prior to the accident, along with Dr. Henry Wu and the others.
