Some people see Edward Teller as an evil figure, whereas others see him as a protector of democracy. In Edward Teller: The Real Dr Strangelove
Peter Goodchild examines the reasons for this dichotomy. He gives information about Teller's early life, but much of the book deals with the years after the Second World War, when Teller was leading the development of the H-bomb, and when he supported the removal of Oppenheimer's security clearance. There is also information how Teller fared in the growing opposition to all things nuclear in the 1960's and 1970's as well as Teller's support for the SDI project in the 1980's.
This is a well written biography, which shows things from Teller's viewpoint, although not in the sense of trying to support his point of view, rather in the sense of trying to find out what motivated Teller to act as he did. Goodchild has also written about Oppenheimer, and here is showing things from the other side of this well known disagreement. In the epilogue he comments that he kept thinking 'if only'. At 400 pages this is a fairly long book and would most suit those who want to dig into the details of this highly significant participant of the Cold War.
