This biography recalls the entire life of Niels Bohr, one of the preeminent scientists of the nineteenth and twentieth centuries; the author even likens his influence to Aristotle's. Though focusing primarily on his scientific life, the book traces his life from his promising beginnings in Denmark until his death in 1962. Also included is the author's assertion that Bohr was nearly able to halt the nuclear Arms race that spawned the Cold War. Other notables that are mentioned in conjunction with Bohr include: James Franck, Lord Rutherford, Werner Heisenberg, Enrico Fermi, Sir John Cockcroft, Ernest Lawrence, and Adlai Stevenson.
