Dear Rabbi Lapin: With reference to my letter of September 30, Rabbi Lamm has informed me that he will be visiting South Africa beginning the first week in February 1964. Rabbi Lamm's itinerary while in South Africa is being arranged by Mr. Misheiker, who is Chairman of the Jewish Board of Education. He suggests that you arrange with Mr. Misheiker to pick an evening (or perhaps Sunday afternoon) when he can speak to as large as possible a group of Orthodox Jewish scientists in Johannesburg. If you have not succeeded in organizing a group by that time, Rabbi Lamm's visit might provide an excellent stimulus for an organizational meeting.Yours very truly,Dr. Azriel RosenteldPresident

Dear Rabbi Lamm, Dr. Azriel Rosenfeld has probably told you that he has written to me and mentioned your name with regard to the Association of Orthodox Jewish Scientists. Needless to say, you are very well-known to me through your writings and the Rabbinical work you have done, and your many achievements. The real purpose of this letter is to tell you how very pleased my wife and I are about your impending visit. I have already spoken to the South African Jewish Board of Education asking them to make arrangements for you to preach at my Synagogue and to spend Friday night and Shabbat with us in our home. It will be a very great honour and privilege for us to have you, and I have a very satisfying suspicion that you will enjoy preaching in my Synagogue. The attendance is an excellent one, and those who come to Synagogue are of a high intellectual standard. I would also like to make arrangements for certain of our members to meet you. I hope that providing the South African Jewish Board of Education is agreeable to this arrangement that it also meets with your approval. In the meantime, if there is anything at all that I can do for you here please do not fail to ask me. I shall be only too happy to be of some assistance to so distinguished a guest. Kind regards, and very best wishes for a happy journey and safe landing in South Africa. Sincerely yours, [Signature]

Dear Azriel: I have recently been speaking with Rabbi Jung about a problem in which I think the A.O.J.C. can make a real creative contribution. As a former student of Chemistry, I have always been intrigued, if not puzzled, by the problem of absorption of different materials with regard to the laws of "Yoreh Deah." Rabbi Jung is interested in obtaining the services of either a Chemist or Metallurgist who will be able to devote some time, with a high degree of competence, to analyzing the absorptive capacities of the various materials currently used for cooking utensils, flatware, dishes, with an eye to using pertinent information in formulating Halakhic attitudes.What I would like from you is a recommendation of an individual or small group of individuals from A.O.J.C. who will be willing to undertake this project in a systematic manner. The goal would be to have the information as presented to outstanding Halakhic authorities, urging them to express their opinions on the basis of scientific evidence, and then to have all the material, scientific and Halakhic, published in NOAM, the Hebrew annual which for the last several years has been devoted exclusively to contemporary Halakhic problems.Rabbi Jung informs me that he is prepared, if necessary, to subsidize a Scientist of real expertness in this field to get the work done responsibly and reliably.Please give it your attention and let me know as soon as possible what your thoughts are on the matter.My kindest regards to your wife and best wishes for good luck.Sincerely yours,RABBI NORMAN LAMM
