June 4, 1962 F. C. Dohan, M.D. University of Pennsylvania 3400 Spruce Street Philadelphia Pennsylvania Dear Doctor Dohan: When we spoke together at Chicago, you were about to tell me of a case of tetraethyllead poisoning (or of alleged or suspected poisoning) in which you were interested, when we were interrupted by the chairman's call to order. I had wished to learn the background of the case, but it was necessary for me to leave immediately after I finished my paper in order to catch my plane. Consequently I had no opportunity to continue our conversation. I shall be glad to have any information which you wish to give me. From your initial words, I gathered that this was something unusual, and there was something in the history, as you began to recount it, that did not fit in to the pattern of a significant degree of exposure to tetraethyllead. This made me all the more interested in pursuing the matter. Sincerely yours. RAK: ss Robert A. Kehoe, M. D. KE 0015326
