"I will feel that the study of this subject is well started, and that fully appropriate steps for meeting the President's wishes have been taken, if the group selected can be brought together promptly, and I hope I may soon have indication of your willingness to serve in this connection."

Vannevar Bush. Letter to Linus Pauling. January 5, 1945.

Linus Pauling. Letter to Vannevar Bush. June 5, 1945.

"Your efforts in this Division have been a great value to the Nation. The development of chromatographic methods of analysis is, in itself, a substantial contribution which is widely used throughout the country wherever investigations of rocket powder are under way. Your studies of stability and surveillance methods have been very helpful in all powder developments and in settling difficulties encountered in manufacturing operations. Your recent suggestion of the use of rate control strands or particles has made the program on castable double base powder much more effective and should give the product a wider range of properties and applications. I believe that you were most helpful in all the Division's undertakings and have every right to feel proud of each contribution."

Vannevar Bush. Letter to Linus Pauling. June 14, 1945.

"We were agreed that the war was bound to break out into an intense struggle, that America was sure to get into it in one way or another sooner or later, that it would be a highly technical struggle, that we were by no means prepared in this regard, and...that the military system as it existed...would never fully produce the new instrumentalities which we would certainly need."

Vannevar Bush. Pieces of the Action. 1970.

"I had a plan for the NDRC in four short paragraphs in the middle of a sheet of paper. The whole audience lasted less than ten minutes... I came out with my 'OK - FDR' and all the wheels began to turn."

Vannevar Bush. Pieces of the Action. 1970.

"There were those who protested that the action of setting up NDRC was an end run, a grab by which a small company of scientists and engineers, acting outside established channels, got hold of the authority and money for the program of developing new weapons. That, in fact, is exactly what it was."

Vannevar Bush. Pieces of the Action. 1970.

"Sam Rosenman and I drafted the order establishing the O.S.R.D. - mostly Rosenman with me hanging hard on the outskirts. The order assigned the N.D.R.C. as one component of the new office, and that assignment brought the only change in the civilian membership of the N.D.R.C. to occur during its lifetime."
