John Darnton has the New York Times in his blood. He was a reporter and editor there for 40 years. Before that, his older brother and his mother worked there. And even more significantly, his father, Byron Darnton, one of the Times most celebrated reporters, died covering the Second World War. John was just 11 months old. He never knew his father, but he does now. He's written a memoir called Almost a Family and in the course of his research was able to unpack the myth of Byron Darnton as the perfect husband, father and journalist.
