[written in left margin, R. Gomory file] Ralph Gomory [stamped, APR 22 1980] lecture./yours of Apr. 14 I would be delighted, but I hope the latter part of September is soon enough. How about the 29th? If not please call my secretary to negotiate a better date. Unless you've heard more than you want to know, I suggest the science and technology of DNA splicing ("recombinant DNA") as the topic. I may be able to add more of the historical framework of its development than has been written about and read widely in the press. If you wish to suggest any alternatives, I'd be happy to discuss it. Thank you for invitation. Yours, Joshua.
