Attorney Kenneth Feinberg, 'What is Life Worth?' As special master of the Federal Sept. 11 Victim Compensation Fund, Feinberg decided how much families of the terrorist attacks' victims would receive and which family members were eligible for compensation. He also was on a team that determined the fair market value of the Zapruder film of the Kennedy assassination. Feinberg has written a book about his work on the Sept. 11 Fund, What is Life Worth?: The Unprecedented Effort to Compensate the Victims of 9/11.
