- The Anatomist (2008, Politico's Publishing, 978-1842-75229-6) the autobiography of Anthony Sampson (which was prepared for publication by his wife and family)
Sampson took an interest in broad political and economic power structure, but saw power as personal. His books read like series of interlocked biographies — of arms merchants, oil company executives, etc., according to the theme of each. He was a biographer and personal friend of Nelson Mandela.
Furthermore, the personal was the psychological. This passages from
The Money Lenders is an example of his psychoanalytical interpretations:
"[Bankers] seem specially conscious of time, always aware that time is money. There is always a sense of restraint and tension. (Is it part of the connection which Freud observed between compulsive neatness, anal eroticism, and interest in money?)"
