THE FOREIGN SERVICE OF THE UNITED STATES OF AMERICA American Embassy, Stockholm, Sweden, April 9, 1959. Dear Josh: Your letter of December twenty-fifth, which must have been written very near the time of the Léwdin party at the dirschfelders', was waiting on my desk when I arrived a month ago. Before I had a chance to look up Dr. Caspersson, I broke my back (no permanent harm done and almost all right by now, thanks), and by the time I was moving around much again, Dr. Caspersson had started on a visit to the United States, from which he returned Sunday. He is coming to lunch with me next Monday, at which time we will be able to talk about problems connected with his particular kind a of prospective space instrumentation. I will drop you a another note after I have seen him. f Now Mary and I have noted the coincidence of your es Nobel lecture with the visit of Wallace and Sonny Brode ~ (he is the Science Adviser to the Secretary of State and hence i, my boss when I am in Washington) May thirtieth to June second. We would like to have a party to which we would invite some Stockholm scientists, iMcluding all those who you explicitly ask to see and excluding all those you explicitly ask not to see. Is that all right with you and Esther? The Brodes arrive Saturday evening, May thirtieth, and leave Tuesday, June second. Since Professor Klein tells me that Dr. B&sdk wants to have you in Uppsala either Friday or Monday, I would suggest that we have the party on Sunday, May thirty-first. If you have made your peace Professor Lederberg -2- April 9, 1959 with Dr. Bédk and would prefer that we have our party June first, we can do that. We hope Stanford life has started happily and that you are having a wonderful time in Italy. Sincer ours Ch J ¢ EB.
