John’s father is Bernard Marx’s boss, the Director of Hatcheries and Conditioning. In Chapter 6, the Director tells Bernard that he once took a woman to the Savage Reservation, and that she went missing. When Bernard visits the Reservation, he discovers that John’s mother Linda is that woman. Because she didn’t have access to contraception in the Reservation, Linda became pregnant with the Director’s child: John. In the World State, having children is considered shameful and disgusting. Bernard takes John and Linda back to the World State in order to humiliate the Director.
