There are a few old buffers like me who five or ten years ago were saying to one another, so and so puts his name on his students' papers, and isn't that shocking. Brian Clark, I think, the distinguished Nottingham geneticist. But we knew the times were changing. I - if you want me to dilate on the subject, let me just express a view. My view in those days was, when it was a question of putting- somebody else putting their names- name on my paper, never. But, fairly recently, within the last 10, 15 years, I've changed my views. It isn't so much a question of my putting my name- or at least perhaps it is- on other people's papers, but it's the feeling that, in those days the scientific world was quite small and everybody really did know one another, and it wasn't too difficult to find your way around. Nowadays, biology is 10 times as big, and without the terminal author who tells whoever work was done, it's even more difficult to find your way round. By looking at papers which have Raff at the end of the paper, I know that they come from a respectable laboratory, but above all, I know about the intellectual- the background.
