“I certainly was not born to history,” Paul Cohen tells us at the very beginning of his book; indeed he wasn’t. He didn’t want to follow his father’s men’s clothing trade, and gave up engineering after one year in university to study the humanities, and even then he did not concentrate on any one part of it. He thought about architecture, then psychiatry and finally the army. None of these, on consideration, were very satisfying, and involved long hours of what seemed to Cohen very boring work.
