This is an edited draft of Baruch's speech, which he dedicates on the first page to Herbert Swope, his speech writer, whom he notes is responsible for much of it. It is his exhortation to the Commission, and to the world, for the necessity of controlling atomic energy, and the steps to such control. Signatures of American delegates at the end are by: John M. Hancock, Richard C. Tolman, Leslie R. Groves, Tom Farrell, F. Eberstadt, Fred Searls, Jr., and Baruch. There is also the signature of Herbert Vere Evatt, the Australian delegate.

These documents cover the years 1847 to 1953, the year of Millikan's death, but the core of the collection consists of the official papers generated by Millikan after his move to Pasadena in 1921. The collection includes more than 125,000 pages of letters, notebooks, unpublished speeches, addresses, lecture notes, and family papers.
