who is the D.H.C?

THE DIRECTOR OF HATCHERIES AND CONDITIONING

The Director opens the novel by explaining the reproductive system of the brave new world, with genetically engineered babies growing in bottles. He loves to throw "scientific data" at his listeners so quickly that they can't understand them; he is a know-it-all impressed with his own importance. In fact, he knows less and is less important than the Controller, as you see when he is surprised that the Controller dares to talk about two forbidden topics- history and biological parents.

The Director comes alive only when he confesses to Bernard Marx that as a young man he went to a Savage Reservation, taking along a woman who disappeared there. She was pregnant with his baby, as a result of what the Utopia considers an obscene accident. The baby grows up to be John; his return to London leads to the total humiliation of the Director.

The Director's name is Thomas, but you learn this only because Linda, his onetime lover and John's mother, keeps referring to him as Tomakin.
