Dear Professor Einstein:
I am returning the contract form herewith. Mr. Maass read it carefully and feels very strongly, as I said to you over the telephone, that it would be unwise for you to sign it. I hope some more effective way may be found for you to make your contribution to the war effort. I shall keep on the lookout and report to you any opportunities of which I may be able to hear.
signed: Frank Aydelotte
