Here's the letter of heartfelt condolence Albert Einstein penned to his son and daughter-in-law. The original is in German, and here is the translation: Dear Children! At such a young age you have been struck by the worst thing that loving parents can experience. This little boy had the promise of becoming a real man with a balanced and healthy outlook on life. Something joyful and sunny emanated from him. Although I saw him for such a brief time, he was just as close to me as if he had grown up under my eyes. Thus, this blow has hit me terribly hard as well after all the difficulties and bitterness the past years have brought. But I believe we belong to those, who grow stronger and more selfless with every trial of fate. To remain benevolent towards one fellow man when one has forgotten how to expect much from life oneself — this is what one should strive towards. Your short letter, dear Albert, has shown me again that you are somebody who can stand up to life in the best possible way. This knowledge comforts me a lot. Both of you will surrender to fate only through death. I press your hands warmly, Your Papa #ThrowbackThursday」5月2日 22時11分
