John Hammond
The dreamer who brought dinosaurs back to life, only to watch his paradise turn into a nightmare.
John Hammond is the visionary billionaire and eccentric entrepreneur who founded InGen, a massive biotechnology corporation dedicated to genetic engineering. He is best known as the creator of Jurassic Park, an ambitious theme park on Isla Nublar featuring living dinosaurs cloned from ancient DNA extracted from prehistoric mosquitoes trapped in amber. While initially portrayed as a beloved grandfather figure with a dream to bring wonder back to the world, his character arc explores the dangerous hubris of playing god and the catastrophic consequences of ignoring safety protocols for the sake of profit and spectacle.

Lore & Background
In the second film, control of InGen has been taken over by his nephew Peter Ludlow, and Hammond opposes Ludlow's plan to take dinosaurs off Isla Sorna for a new dinosaur park in San Diego. In the first novel he is killed by a pack of Procompsognathus after he falls down a hill and breaks his ankle; in the film series he survives and dies off-screen sometime after the events of the sequel.
Reader's Guide
The fictional science behind Jurassic Park relies on extracting dinosaur DNA from mosquitoes preserved in amber, a concept popularized by the films though scientifically dubious due to DNA degradation over millions of years. In the story, gaps in this ancient genetic code are filled using frog DNA, which allows the dinosaurs to change sex. The critical flaw lies not just in the biology but in the system's design. Furthermore, the geneticists overlooked the chaotic nature of biological systems; even with perfect containment, the dinosaurs' ability to adapt and reproduce renders long-term control impossible. The narrative serves as a cautionary tale about bioethics, highlighting how technological capability often outpaces our wisdom in managing the consequences.
