Letters Sent to C.B. [C.B. Lee], April 16, 1930

April 16th, 1930. Dear C. B.: I have today discussed the matter of the Government investigation of the various Clock Companies, with Dr. Flinn and will give you the picture as it exists briefly so that you may form your own opinion as th what extent you wish to discuss this matter while at Elgin. In order to present the matter with some unity, I will discuss the situation with reference to the various Clock Companies separately: of the girls he INGRAHAM: Mr. Knowles advised Ingraham that one/tested was radioactive. This particular case Dr. Flinn had examined several times I believe, but did not find her to be active. I understand that Ingraham has had some correspondence with the Department of Health with reference to this case, but as yet no definite conclusions have been arrived at. As far as we know this is the only case which the Government found active at Ingraham. It seems that during the progress of the work here both Knowles and Schwartz were advising Ingraham as to their findings, but when Washington became aware of this fact they requested that no further information be given to the Clock Companites. Ingraham did not respond any too well to such procedure. WATERBURY CLOCK: As I understand the situation from Dr. Flinn, there has been no official statement made by the Government to individuals regarding their findings here, but it would appear that there has been considerable loose talk by Mr. Knowles relative to what he did find. They advised the Materbury Clock Co. that Nrs. Pickett was radioactive. Dr. Flinn has examined Mrs. Pickett prior to the Government examination and since, but found her negative both times. Mr. Knowles told Dr. Flinn that he found a girl by the name of Belle Wallace, as well as three or four others, names of whom Dr. Flinn does not recall, active. None of these cases had been found active by Dr. Flinn and most of them had been examined at several different times. Granger told Dr. Flinn that he ran a blank in on Knowles, and after linowles hnd completed the test Granger asked him whether or notsh was active, and Knowles stated that she was. lis. Koss, a recognized case was tested by Knowles and Knowles reported thothe Clock Company, as weel as her attending physician, that she was virtually a mesothorinm case, and that practically all of the activity found could be ascribed to Meso. Neither Dr. Flinn or I are able to foretell how he arrived at such a conclusion. Knowles also has made the statement that the alpha ray test is often negative when the gamma ray test is positive, but that if he finds the gamna ray positive he con- siders the pationt active. NEW HAVEN CLOCK: Mr. Knowles has made the statement that he found Ton Chamberlain active - Dr. Flinn has examined Chamberlain on two different occasions and found him negative both times. We have no difinite information that any of the operators were found active.
