D O C U M E N T S 4 6 6 , 4 6 7 J A N U A R Y 1 9 2 7 4 5 9 My family told me about the pleasant hours they spent with you. I hope you have amicable recollections of that surprise attack in Japan. I hear that our young friend Suzuki-san visited you. It would interest me very much to know your—real, not tainted by Japanese courtesy—judgment of the violin that he brought with him for you. The elder Suzuki is a very interesting, genuinely Japanese gentleman of the old school. Although he has been making the most un-Japanese of all instru- ments, the violin, for 40 years, he does not understand European music in the least and is [nevertheless] at the same time a very expert evaluator of a violin’s sound. In anticipation of your kind responses and with best compliments also to your wife, I am sincerely yours, Leonor Michaelis 466. To Paul Ehrenfest [Berlin,] 27 January 1927 Dear Ehrenfest, I find your examination very nice and think that Fermi’s theory has gained much plausibility because of it. Have you seen Debye’s notice in the “M. Wien is- sue” of the Annalen? He shows there that by demagnetizing gadolinium sulfate one can achieve a substantial drop in temperature below hitherto attainable tem- peratures. Warm regards, your Einstein Albert has certified for his Diplom degree. On Feb. 1st he’ll be taking up a po- sition in Dortmund. He sends his regards, likewise the womenfolk. 467. To Mileva Einstein-Mariü [Berlin, 27 January 1927] Adn has become a fine specimen, a real man who knows what he wants (un- fortunately, also does what she wants). I did not pester him much but did tell him with great seriousness my opinion about offspring. Whether it will help, I don’t know, since he is not expressing himself. Warm regards to you and Tete from your Albert Tete’s military note gave me very great pleasure.
