John Parker Hammond, was the CEO and creator of Jurassic Park. He founded the company InGen and the Hammond Foundation. He had at least one daughter, two grandchildren (Tim and Lex Murphy), a sister (as Hammond's nephew has the surname of Ludlow, not Hammond) and a nephew, Peter Ludlow. It was revealed in Jurassic World that Hammond has died sometime ago and a memorial statue of him is built in the new park, Jurassic World. He would have appeared in the film but Richard Attenborough passed away before he could film any scenes for the film.
- In the Brazilian dubs of Jurassic Park and The Lost World: Jurassic Park, he was voiced by the late Orlando Drumond, who also voiced Thing, Sabretooth, Desaad, Lex Luthor, Sinestro, Scooby-Doo, Pops Racer, Santa Claus, Palpatine, Baxter Stockman and Gandalf.
