Dr. Alan Grant

Protagonist in Jurassic Park

Originally A Paleontologist

Very intrigued by dinosaurs, he spent his life researching them and digging up their bones. When he is brought to Jurassic Park it is an absolutely mind blowing experience for him. He had spent his whole life digging up skeletons of creatures that lived millions of years ago and now he suddenly sees them living and breathing right before his eyes.

Dr. Grant and the kids

At the beginning of the movie he states that he doesn't care for children much, but one of the main conflicts in the story is him protecting the grand children of Dr. Hammond with his life.
