Lederberg Stanford University of Medicine Department of Genetics Stanford University Medical Center Stanford, California 94305 U.S.A. 1) + Dear Josh: 8S > . . o“° Sorry, I can't help you. Although I was a graduate student at 6 Stanford during the critical period (1939-42), I worked entirely at the “” Marine Station, and was consequently not familiar with what went on in - the Biology department on campus. My first recollection of the Neurospora D project is an informal talk to van Niel's group (probably in Kees’ house) 4 by Ed Tatum, when the first auxotrophic mutants had already been isolated ; this was no doubt in late 1941 or early 1942. < ¢ Have you consulted Kees and Lawrence Blinks ? I know that Kees was much involved in the restructuring of the biology curriculum that followed creation of the School of Biological Sciences ; and he may therefore have some recollection of the Comparative Biochemistry course to which you allude, and about which he would very likely have been consulted by Ed Tatum. It is hard for me to believe that no records for those years of the activities of the Department (or School, as it then was) have been preserved. I wonder whether Lawrence Blinks might not be able to help you out about this, either from his own records or from the archives of the Marine Station. Perhaps worth a try. Failing any additional information, I don't see any reason to doubt Beadle's published account of the genesis of the project. All the best, R. Y. Stanier J
