Graham Chainey may have revelled in the shooting sticks of brilliant talk during his time at Oxford, but his circle was somewhat restricted: nine historians, five philosophers, five dons of literature, two classicists, and an Anglo-Saxon. Perhaps it is just a further illustration of the two cultures that – nearly 50 years on – I recognised only 11 of his “22 household names”, but think that I would, in 1966, have recognised only six, and one of them only because he wrote two best-selling fantasy novels. The world of the science laboratory is a long way from shooting sticks along Parks Road.
