October 14, 1961 fr. Frederick Stone Diviston of General Medical Sctence National Institutes of Health Bethesda 14, Maryland Dear Fred: Partly with the Impetus of the work we have undertaken In excblology with NASA support we have been becoming keenly aware of the unmet opportunities In medical Instrumentetton, Dr. Eliott Levinthal has bean working closely with me on our exobiclogy prefect and Is especially competent and Interested In the development of this area. We are now facing the need and possibility of some enlargement of our instrumentation engineering program for axobiclogy. However, | hesliate to encourage much further expansion of this activity except In the context of a more generally useful app! tcation to the research problems of the medical school. Many very specific useful connections have become apparent. For example, there are some unexpected parallels in the engineering solucion to the problem of the selective detection of microorganisms seen through a microscope and the efficient utilization of fiuorescopy with the assistance of image Intensifler techniques. In both Instances a sophisticated under~ standing of video electronics and information processing is required. Many other points of common Interest betwean the exoblology program and other activities in our depertment and elsewhere throeughcut the medical school are beginning to emerce. “Ye were therefore particularily interested to hear of the additional support for medical instrumentation that was incorporated into the recent NIM appropriation. { belfeve that tt would be espectally appropriate If support for our expanded activities In this field could be undertaken Jointly by NASA and the NIH. We are far from the stage of explicit proposals and | gather that no very definite program has yet been formulated In the NIH to handle these new directions. However, we would greatly apprectate being well informed as to your program developments. 4 '2nele Dr. Levinthal will be In Washington In ten days or so and i would regerd 1t ss a very helpful courtesy If he could obtain any additlonel Information or have some opportunity for the most tentative discussion with an appropriate member of your staff, With best regards, Yours sincerely, Joshua Lederberg Professor of Genetics enc: (1)
