On 4th November 1915, Einstein just finished his two pages masterpiece on theory of general relativity. The great, work which earned Einstein the fame and glory of a genius. In 1915 when Einstein was 36 years old and living in the Berlin (Germany) while his separated wife Mileva with two children Hans Albert Einstein and Eduard Tete Einstein was living in Vienna (Austria). With the joy of achieving something great in the field of physics, Einstein wrote a letter to his children. The relationship between Mileva and Einstein became murky and Mileva did not even want Einstein to have interaction with children. She used to have an eye on the letters, Einstein used to write and filter those letters. Einstein was desperate to get in touch with the children and wanted their attention. Here is one of his letters to his 11 years old son Hans-
My dear Albert,
Yesterday I received your dear letter and was very happy with it. I was already afraid you wouldn’t write to me at all any more. You told me when I was in Zurich, that it is awkward for you when I come to Zurich. Therefore I think it is better if we get together in a different place, where nobody will interfere with our comfort. I will in any case urge that each year we spend a whole month together, so that you see that you have a father who is fond of you and who loves you. You can also learn many good and beautiful things from me, something another cannot as easily offer you. What I have achieved through such a lot of strenuous work shall not only be there for strangers but especially for my own boys. These days I have completed one of the most beautiful works of my life, when you are bigger, I will tell you about it.
I am very pleased that you find joy with the piano. This and carpentry are in my opinion for your age the best pursuits, better even than school. Because those are things which fit a young person such as you very well. Mainly play the things on the piano which please you, even if the teacher does not assign those. That is the way to learn the most, that when you are doing something with such enjoyment that you don’t notice that the time passes. I am sometimes so wrapped up in my work that I forget about the noon meal. . . .
Be with Tete
kissed by your Papa.
Regards to Mama.
