Dennis T. Nedry was a computer programmer at Jurassic Park. Due to his financial problems and low salary, he accepted an offer from Biosyn to smuggle dinosaur embryos off the island. His last name is an anagram of nerdy.
A corporate scientist from Biosyn, Lewis Dodgson, hired Dennis Nedry to steal embryos from Jurassic Park while on Isla Nublar, so that Biosyn could clone its own dinosaurs and catch up on InGen's 10 years of research.
Dodgson met with Nedry in San Jose, Costa Rica to discuss the arrangement and give him the equipment to complete his task: a can of shaving cream with a secret compartment that could hold 15 species of dinosaurs. Using his skills, he engineered a series of computer errors to get him past security and to cover up his tracks. Unfortunately, he shut down all the electric fences in the process, except those keeping the Velociraptors inside their pen, throwing the park into chaos and causing the deaths of much of the Jurassic Park staff, ironically including himself.
Due to a tropical storm, he got lost on his way to C-3208 ship at the docks and accidently crashed his gas-powered Jeep and while trying to sort the problem out, was confronted by one of the dinosaurs he had released: a young Dilophosaurus. He anxiously tried to get away from the seemingly harmless dinosaur, but it soon afterward revealed its true colors by getting angry and "frills" him.
The Dilophosaurus vomits its poison on his chest, then his eyes. When he finally does get back in and locks the car, the Dilophosaurus sneaks up and surprises him. The Jeep then violently shakes back and forth continuously. He bangs, screams and yells as the Dilophosaurus starts devouring him alive.
