Danish physicist (1885–1962) who was awarded the 1922 Nobel Prize in Physics for his theory of atomic structure. TLS in Danish, one page, 8.75 x 11.25, University Institute for Theoretical Physics letterhead, November 2, 1945. Letter replying to an invitation to lecture, in part: "Thank you for your kind letter with the invitation to give a lecture at the Officers' Association. I am very sorry that I will not be able to give such a lecture, as all my time and energy are completely absorbed by the work that has accumulated during my long absence, and I have therefore had to decline all invitations to give more lectures than those I committed to immediately upon my return home. However, I have heard that my long-time colleague here at the Institute, Dr. Jørgen Koch, has agreed to give a lecture at the Sub-Lieutenant Association, and I believe that he would gladly also speak at the Officers' Association if desired. In that case, you might write to him yourself, or if you prefer, I will gladly speak to him about the matter." In fine condition.
