Dr. DZIEMIAN. I couldn't say. Mr. SPECTER. Is it a highly individual matter as to the reaction of an individual on that subject? Dr. DZIEMIAN. I don't know. Mr. DULLES. But take a wound like the wrist wound of Governor Connally. He couldn't get that without knowing it, could he? Dr. DZIEMIAN. I think he said that he didn't know he had a wrist wound until much later. (Discussion off the record.) Mr. SPECTER. I have no further questions of Dr. Dziemian, Commissioner Dulles. Mr. DULLES. Thank you very much. TESTIMONY OF DR. FREDERICK W. LIGHT, JR. Mr. DULLES. Doctor, would you give your full name? Dr. LIGHT. Frederick W. Light, Jr. Mr. DULLES. Would you raise your right hand? Do you swear that the testimony that you will give before this Commission is the truth, the whole truth, so help you God? Dr. LIGHT. I do. Mr. SPECTER. Dr. Light, the purpose of asking you to appear today is to question you concerning the results of tests taken at the Edgewood Arsenal. With that brief statement of purpose, I will ask you to state your full name for the record, please. Dr. LIGHT. Frederick W. Light, Jr. Mr. SPECTER. What is your business or profession, sir? Dr. LIGHT. I am a physician specializing in pathology. Mr. SPECTER. What is your educational background? Dr. LIGHT. I have an A.B. from Lafayette in 1926, M.D. from Johns Hopkins Medical School in 1930, and Ph. D. from Hopkins in 1948. Mr. SPECTER. Would you outline your experience since 1933 in a very general way, please? Dr. LIGHT. Well, in 1933 I was still at the Reading Hospital, resident in pathology. Between then and 1940 I was pathologist in Clarksburg, W. Va., and later in Springfield, Ill. In 1940 I returned to Johns Hopkins University to study mathematics for awhile. Mr. DULLES. To study mathematics? Dr. LIGHT. Yes. And then in 1952, or 1951, excuse me, I began working at Edgewood Arsenal where I am at the present time. Mr. SPECTER. What have your duties consisted of while working at Edgewood Arsenal? Dr. LIGHT. Primarily the study of pathology of wounding. Mr. SPECTER. What is your formal title there now, Dr. Light? Dr. LIGHT. I am chief of the Wound Assessment Branch and assistant chief of the Biophysics Division. Mr. SPECTER. And what is your relationship to Dr. Olivier and Dr. Dziemian? Dr. LIGHT. Dr. Dziemian is the chief of the division. Dr. Olivier is chief of one of the branches, and I am chief of one of the other branches. Mr. SPECTER. Have you been present here today to hear the full testimony of Dr. Olivier? Dr. LIGHT. Yes. Mr. SPECTER. And were the tests which he described conducted under your joint supervision with Dr. Olivier? Dr. LIGHT. Only a very general way. I wouldn't want to say I supervised him at all. We discussed what he was going to do. Mr. SPECTER. Would it be more accurate to state that you coordinated with him in the tests which were under his general supervision? Dr. LIGHT. Yes; that might be stretching it a bit even.
