28 September 1978 Dr. Joshua Lederberg President The Rockefeller University 1230 York Avenue New York, NY 10021 Dear Josh, I'm not sure if this "Snailmail", as some people at Carnegie-Mellon describe standard letters, will reach you before my computer msg. In any case, there are only a few letters of recommendation left to complete for the remainder of the agencies I'm applying to. If you think Karen has all the necessary materials to do this already, please send her the enclosed materials and me a computer message. Specifically, this is what is needed: 1) The NATO (NSF) fellowship letter of recommendation on the form provided. Deadline is 20 November. 2) A letter for the National Multiple Sclerosis Society following the suggestions as outlined in the letter I've enclosed. 3) A letter to the Muscular Dystrophy Association, Research Department, 810 Seventh Avenue, New York, NY 10019. The letter should contain "concise evaluations of the abilities and scientific interests of the candidate". Hope all is going very well in NY. Regards to the family. Thanks again (as N approaches infinity). Sincerely yours, jong J Jerry Feitelson
