It Is a great pleasure to comply with your recent request for a letter in support of your pending application for a visitor's visa to the United States. " Z should lita to review our past relations from tw5,,angles. Our first meeting In 1945 was aolely in ay capacity as a member of an investi^ctinQ teem for the Chemical Warfare Service of the U. S. Army. The following meetings were In xay capacity as a Research Director for Che Dow Chemical Company, later ea Technical Advisor to the president of Dow and finally as a CornealCent. ' '' ' During the early part of 1945, I was on leave from Dow to serve as a camber of a team vhith, under the auspices of the Chemical Warfare Service of tho U S, Army, was to study the chemical Industry of Germany, more particularly, in so far as it could be of interest to Chemical Warfare In the still active war with Japan. 1 had spent a good part of the month of Kay and June on investigations in the northern part of . Germany and hod returned to our headquarters in London to write my reports. While there an order reached me during July to immediately proceed to Heidelberg, Germany, for investigation of the large I, G. unit at Ludmigchafen, formerly B.A.S.F., then under American occupation. Shortly tkeroafter, thin (J^eQuho Qurned over to French occupation, and on my arrival in Heidelberg, the U. S. Army Connand furnished me a letter of introduction to the French Commander at Ludwigshafen asking `t&ca to give aa any assistance in my mission. You will remember that on my arrival in Ludwigshafen, the French Commander, Col. Weiss, immediately introduced os to you, telling me that you would be in the best position to furnish the information I needed. One of our first discussions concerned the development of rocket fuel. You raferred C3 to Dr. Hausoozm, the llaisop agent between the government laborator^cat Peanetnindo and the I. G. specialists, who arranged co interview with Lt. Col. P. R. Tarr, the chief of the Intelligence Division for Chemical Warfare in Europe and myself, which resulted in obtaining complete and satisfactory reports. The next item was Chemical Warfare's interest in -CttSi starve gaeca developed and manufactured by the Germans ( ' 'fir. Otto Aabroo 2 . July 21, 1967 You ucdortook immediate atcpo to summon all technical personnel engaged In thio development for sectings vlth Chemical Warfare officers and conoulcaneo which lasted several days and were conducted at CarbageCourt-Center at Kohlhof near Heidelberg, Complete and detailed reports on the chemical and engineering phases of this development were written by two of my colleagues, .Dr, J, Kern and Hr, G. Fanero, which have naver been debl&oalfiad. Another item of interest in my mission was the pfChlcsa of synthetic rubber (Buna) developed and manufactured in several locations. Nobody would have been better qualified than yourself in this matter since it was well Known that you had been connected with this development at its inception beginning, with a study of natural rubber in Malaya, The reports we received through your efforts were of great value to the sub sequent development of synthetic rubber in the United States, In addition to these specific Chemical Warfare items, we discussed many chemical developments, and it was only natural for me to tell you in ' parting that I would look forward after conclusion of the peace treaty in continuing our relations as a representative of Dow. 1 returned to Europe in September, 1949, on another government miscion as a delegate to an international meeting on "Saw Materials for Atomic Energy" held in London. At the end of the session, I visited the continent on matters of Interest to Dow and my first et(|p was at LudvlgOhafen. Unfortunately, cs a result of the outcome of the Munich trials, you could not be present, but owing to my acquaintance with B,AStFpppiS?d2el in 1945, X had a cost cordial reception. Within one year my visit was returned by B,A.S.F.personnel at Midland, Michigan, and 1 believe I can say that already then the groundwork was laid for a closer relations between and B.A.S.F, resulting in 1956 to the organization of a joint company /""Dow-Badioche." * From 1952 on, I hod the assignment of taking annual and even bi-annual trips to Europe In Dow's interest. Our pleasant relations were soon shared by other Dow personnel and many foaifcful meetings resulted from it. Only lact year, Dow was fortunate in having you as their guest in Sarnia, the eeot of Its Canadian aubsidlery. Moreover, it is a wellknown fact that a man of your attainments has many other national acd international connections In the Industry. In c2alslon, I wish to express my conviction that your cooperation was of great benefit to the U, S. Army and the United States Government immediately after tho-ssar crbsaquently to American Industry in spite of the handicap of' travel- restrictions* which I hope will be dl?continued.
