John Forrester (25 August 1949 – 24 November 2015): A brief personal memoire. -- During my years in HPS Cambridge we always struggled to bring together the two sides of the department: history and philosophy. John was the only member of staff who fully lived the synthesis. But he did so at the price of occasionally being eyed sceptically by both “camps”. He was a little too “continental” for the philosophers, and a bit too "foucauldian-speculative" for most historians. Fortunately, he didn’t suffer as a result: he cherished being “the odd thinker out”. And he had developed it into a fine art. Once, after we had taught a seminar together, he asked me what I thought of his contributions to the class. I stand by my answer: “20% of what you said was utterly brilliant.” My reply pleased him, and I meant it as a compliment. -- I also liked John’s personality. I asked him to introduce me when I gave my inaugural in 2003. And I was touched when, as head of department, he wished me farewell in the context of my valedictory lecture in 2009. He had great personal warmth. It set him apart from the rest of us.
