I want to know the answer to the following question:
Who authored Whitehead's biography that is considered to be the most reliable description of Whitehead's life?
All the background I'm provided with is that "Additionally, Whitehead was known for his "almost fanatical belief in the right to privacy", and for writing very few personal letters of the kind that would help to gain insight on his life.". Is that enough to answer the question?
Answer: no
