Lieutenant General Sir Frederick Edgworth Morgan was controller for atomic energy during Britain’s crucial period of 1951 to 1953. In a private letter to his successor in mid-1955, we find out what Christopher Hinton thought of him:

It is on the question of salaries that I seriously disagree. All of our worst troubles when we were in the Civil Service arose from their unwillingness to pay reasonable salaries to the higher staff. It was this that condemned us to having a man like Freddy Morgan in charge of the organisation.
