British atomic manufacturing supremo Christopher Hinton had a fearsome reputation that comes down to us more though asides and a handful of descriptions than from direct recollections. His diary is invaluable although generally cautious. But in this 1954 diary entry I catch him commenting on a non-executive director of the Atomic Energy Authority:
There was a tough discussion about exchange of information with the U.S. – I was opposed by [XXX] & Cockcroft – I doubt if the former has any idea of the problem or will get one.
