Dr. Hanna Gray Pres. U/Chicago [stamped, JUN 17 1989] G.W. Beadle papers/archives. Dear Hanna -- APS has asked me to write a brief memoir on Beadle. My focus will be on the scientific revolution (not a Kuhnian) he and Tatum wreaked in 1941; but I should include a paragraph or two on his term as president of U/Chi. As a historian, you will know what I need by way of sources; but I am not (now) writing a detailed biography; so I would welcome even your [mark to note, (or hand this over to your PIO/archivist. If there are any published assessments of that era they would be quite helpful.)] own draft on a non-attribution basis. With best regards, Joshua. P269 with p 269 6/20/89 arr
