Kehoe, M.D. Dept, of Preventive Medicine University of Cincinnati Cincinnati, Ohio Dear Bob: I want to write promptly and thank you for the very careful and complete answers to earlier questions I received in your letter of April 13, 1965. It will, of course, be some time before I can completely absorb all the data and then I will want to write to you again my understanding and appreciation. About Clair Patterson, let me say that he is a very intense, interesting man to whom I am sure you would enjoy talking. He is impatient and restless, and wants to get on with the ideas that seem most impressive to him. He was working here in the Geology Department temporarily on a leave of absence, and the head of the department asked if I would talk with him, which I was glad to do. We went over with him a number of times what data are available in the industrial disease reports and tried to give him guidance in development of this manuscript you refer to. He has become impressed with the increasing amount of lead in the water from his studies of snow and ice. He has gradually reached the conviction that he should write on the subject. I think if you were to meet him you would find him interesting and extremely modest. - I hope this interpretation is helpful to you. Let me urge you to correspond with him freely, and perhaps some time arrange to meet him. With best personal wishes, I am As ever yours, HLH:rt Harriet L. Hardy, M.D N22403
