N e w Y o r k .N.Y. Ill January 22, 1935 Mr. M. F. Judd, Secretary, Raybestos-Manhattan, Inc., Bridgeport, Conn. Re: Mellon Institute of Industrial Research ______ Symposium on Dust Problems__________ Dear Mr. Judd: As I indicated to you over the telephone this afternoon, I am enclosing a copy of a memorandum I prepared for Mr. Lewis H. Brown regarding my trip to Pittsburgh last Tuesday, January 15th, to attend the Symposium on Dust Problems held under the auspices of the Mellon Institute of Industrial Research. VB:T Enclosure 0 1935 Vandiver Brown Attorney Vi VdnOIl/J.'DlI I'LL:-- MELLON IMCITTOTE OF INDUSTRIAL iu: sea?>ci siiiPocruLi on dust ___________________PP.03LSJ3 - PITTHRIIKOH- JAN.15- 1035 On or about Deccabor IE, 1934- the Liollon Institute of Industrial Research addressed letters to some 05 industries having industrial disease problems inviting then to attend n meeting to be held under the auspices of the Institute on the 15th day of January. One of these invitations was received by the Asbestos Institute and, although the Asbestos Instituto did not accept and was not officially represented, Johns-Uanvillo Corporation requested and obtained permission to send a repre sentative* The invitations expressly stated that ''attendance -at this meeting need entail no obligation". Johcs-'/anvillo was represented at the meeting by the writer of this memorandum. Approximately 250 people were present ropcsenting over 50 industries which had accepted the invitation of the Mellon Institute. The Mellon Institute was greatly surprised at the remarkable* response and it is my opinion that one cannot find a better indication of the serious nature of the problems it was the purpose of the meeting to discuss. I r?ns able to ascertain that the Mollon Institute had boon prompted to call, the meeting by representatives of the sand and glass and the refractories industries. Represen tatives of these industries conferred with Hr. E. R. Violdlein, Director of the Instituto, and after advising him of the nature of thoir problem, of its wide-spread character and numerous menacing aspects, suggested the need of some form of concerted action on the part of those industries presently or potentially involved. I understand that Hr. F. Yi. Sherwood, Vice-President of Owens-Illinois Glass Company and Hr. Roger Rltchlns, Presi dent of the American Refractories Institute, were the porsons who presented the situation to the Mellon Institute. Ur. v?eidlein, on behalf of the Instituto, agreed to cooperate to the extent of calling the meeting and having the representatives spend a day in Pittsburgh as the guests of the Institute. There was some preliminary discussion as to the possibility of using the Mellon Instituto as a clearing house for information and research upon aspects of the problem common to all industries but do finito coaisitaonts v/cro postponed until after the holding of the meeting. An impressive lint of experts specialicing upon vnriou.3 aspects of the dust problem attended the meeting and $ M I `-M \ b > A t -2 - delivered addresses. Anoxia those were Hr. A. C. Birth, a lawyer cisco elated with V/illiaas, Ever3oan and Uorgan, Toledo, Ohio, attorneys for O-gans-Illlnola 01a3s Company; Dr. Eugene P. Pendergra'33" or~the X-ray Laboratory, University Hospital, Phila delphia; Dr.__A. J. Lanza. Assistant Hedtcal Director of the Hetropolitth "Life Insurance Company; Dr. R. R. Sayers, Ltedical Officer in Charge of U. s. Public Health Service; Professor Philip A. Drinker of the School of Public Health, Harvard Universityf U r F . Robertson Joneg, Ceneral Manager, Association of Casualty and Surety Executives; and Ur. Donald E. Cummings, Assistant Director, Saranac Laboratory for Study of Tuberculosis. The addresses delivered by these specialists, togethei with the open discussion that followed then, revealed, among othei things, the very menacing character of the problem, its complex nature, the uncertainties attending most of its aspects and the necessity of some form of united action by the afflicted industrii It was recognised that some aspects of the problem were peculiar to special industries but it was equally evident that other aspects were common to all. For example, only two forms of dust, namely, free silica and asbestos, are definitely known to produco disabling fibrosis of the lung. Even in the case of theso dusts the problems resulting therefrom are quite different since the fibrosis resulting from silica is of a much more 3Grious character than that resulting from asbestos in that the former predisposes to tuberculosis and i3 much more likely to have a fatal termination. On the other hand (and this illustrates one of the most serious aspects of the problem that is common to all dust producing industries) the fact that no other dust is known to produce disability ha3 not prevented entirely groundless claims aggregating millions and even hundreds of millions of dollars being brought against Industries which have no silica or asbestos uu3t hazard. For example, Dr. Lanza pointed out that no one had ever maintained that gypsum dust was harmful and yet, nevertheless, the gypsum industry had suits pending against it covering claims in excess of four million dollars. It appeared that among the problems common to all industries were the following! (l) The menace of ambulance chasing lawyers in combination with unscrupulous doctors. The uncertainties surrounding diagnosis of any of the various forms of pnoumonoconiosis are so many that a question of fact is presented in every ease. Expert testimony can be pro duced by both plaintiff and defendant and it is for the Jury to decide whose experts are *0- correct in their interpretations. In making this decision, the jury is not likely to favor the opinion of the experts produced by the employer. (2) The desirability of ranking various dust diseases compensable under properly drawn workmen's compensation laws. One of the speakers stated that nthe strongest bulwark against future disaster for industry is the enactment of properly drawn occupational disease legislation". Such legislation would (a) eliminate the jury and empower a Medical Board to pass upon the existence of the disease and the extent of the disability; (b) eliminate the shyster lawyer and the quack doctor since fee3 would bo strictly limited by the law; and (c) permit the correct ing of initial mistakes in the making of awards by providing for hearings to reduce or eliminate awards if proof could be adduced that the claimant was not disabled or that the extent of his disability had been over estimated* (3) Problems of ventilation, dust collecting and elimination, and respiratory devices. (4) The establishing of standards (a) for dust counting and particle sise determination, (b) for the taking of X-rays for diagnostic use, and (c) for the interpretation of the markings on the films so produced. At the close of the discussion a Hr. Kurts, VicePresident of American Refractories Corporation, made a notion that Hr. William P. Yant, Chairman of the meeting appoint a nominating committee who would nominate a group of individuals to servo as a committee for the formulation of ways and means to brinfr about effective cooperation of some character between the various industries for meeting and combating those phases of the dust problem common to all. This notion was carried and a Nominating Committee appointed which retired and upon returning presented to the meeting the names of seven individual', to act as such Committee. Iio other names having been placed in nomination, the following were elected to act an the Committe< and report back to the various industries and groups represented at the nesting ot* to who the invitation had been originally extended: -4'** Vandiver 3rown representing Asbestos, Cork and Non-lietallic Dr* B* B, Saklatwalla representing Chemical, Abrasives, Alio: and Non-ferrous metals E. 0. Jone3 representing Foundries A# Y?. Gherwood representing Glass Sand, Ground Sand and Glas: Manufacture A. J* Gentholts representing Iron, Steel and Ores A, J. R. Curtis representing Lime, Limestone, Cenent and 'Gypsum Roger A, Hitchins representing Refractories,Ceramics and Cl I explained to the other members of the Committee that I had been sent to the meeting solely as an observer and had no authority from Johns-Manville Corporation to accept membership on the Committee and certainly none from the Asbestos Industry as a whole. I was urged, however, to meet with the Committee and agreed to do so on the condition that I might withdraw if approval of my serving in that capacity should not be forthcoming* I pointed out that members of the Asbestos Industry did not care to be associated in the minds of the pubii< or of employees with those industries whose problem was bilicosi: and that for this reason I felt there night be some opposition t having a representative of the Asbestos Industry working with them. I did indicate, however, that I realized numerous aspects of our problem were the same and that if cooperation could be worked cu.t without an undue amount of publicity, Johns-Uunville Corporation and perhaps the Asbestos Industry ha a whole, would in all likelihood bo willing to cooperate. It was the opinion of the Committee that this condition would not present any insuperable difficulty* Mr* Roger Hitchins, President of American Refractor ies Institute, was made Chairman of the Committee which held a moeting Tuesday evening after tho close of the Symposium. Ur. Iiitchin.3 was designated to meet with Ur. Y/eidlein of the Mellon Institute and ask him to make a proposal in definite and concreti fora as to the wanner in v/hich tho Mellon Institute might bo able to assist tho various industries for a fee of t 25,000. When this proposal has been received and approved by the members of the Committee, it will be submitted to '.lie various industries with tho recommendation that it be accepted end that the v viou industries or individual corporations agree to stand good fur a proportionate amount of the fee not in excess of a defiuite specified suu. -5 - I gathered that the proposal which would bo made by the Hellon Institute would includo, among others, the follow ing: (a) The compiling of a comprehensive bibliography of all book3, treatises and publication's deal ing with any aspect of the dust problem; and the evaluation thereof. (b) The compiling, digesting and correlating of data and information from various subscribing industries relative to their particular experi ences. (c) The drafting of approved workmen's compensation legislation covering pneumonoconiosia. (d) The digesting of the laws of the various states which might affect the operations of industries presenting a dust hazard. (e) The outlining of problems requiring research or the establishment of fixed standards and the prevention of duplication of effort and expense along these linos. The interest with which the discussions were followed and the enthusiasm which greeted the proposal for unified effort lead me to believe that the necessary support will be found for some sort of program along the above lines.
