You know that I have been extremely eager to have your help in this work. I think perhaps you have not fully realized how much I appreciate your administrative experience and obvious administrative wisdom, nor how aware I am of our need for just this in the present project. Perhaps too you do not evaluate highly enough the fact that you have worked so much in neutron physics, and that you are so well informed about the last year's developments at MIT. These three qualifications make you, in my opinion, very nearly unique. In addition, I want to express in writing my own confidence in your stability and judgement, qualities on which this stormy enterprise puts a very high premium.
