UNIVERSITY OF CALIFORNIA COLLEGE OF AGRICULTURE AGRICULTURAL EXPERIMENT STATION DIVISION OF BOTANY LOS ANGELES 24, CALIFORNIA April 2l., 1951 Dre Joshua Lederberg Department of Genetics University of Wisconsin Madison 6, Wisconsin Dear Josh: The AEC has awarded me a postdoctoral fellowship. However, the avard was made in accordance with my original NRC application. It appears that the AEG award was based upon the recommendation of the NRC, for it was made before the AEC received my letter of April 10th informing them of my intention to work with you. The AEC Fellowship Board will decide shortly if I am to be permitted to use the award for an investigation in bacterial genetics. If they do not aporove my ammended research vlan I shall have to refuse the fellowship and wait until I hear Brom the PHS, the last fellowship opportunity. As soon as I hear from Oak Ridge I shall inform you post haste. CD yours ; + ReP. Levine
