Humphry is the author of 11 books, including the best selling Final Exit.
From an interview with Anthony Qaiyum on October 30, 1995 for Tripod:
Tripod: I understand that you've had trouble with religious groups. Which ones have been your biggest opponents?
DH: The Roman Catholic Church. It's a dedicated opponent.
Tripod: If you don't mind my asking, would you describe yourself as a religious person?
DH: No, I'm an atheist.
