To Friedrich Heilbron 1 June 1922 In response to Abs. 197, informs that he accepted the invitation to the meeting of GDNÄ upon Max Planck’s repeated urging. Stepping back would enhance the tension between him and a part of leading German physicists. TLC. [43 147]. 256. IE to Julius Hoffmann 1 June 1922 AE refuses to write introduction to the German edition of Nordmann 1921a and feels he has been put in an embarrassing position.
