A letter written around 1929 by Albert Einstein to his son Eduard (nicknamed “Tetel”), discussing his progress in solving the Unified Field Theory will be auctioned by RR Auction in Boston, estimate yield: “$100,000+.”
According to the RRA website, in 1924, Einstein finished laying the essential groundwork the Unified Field Theory, an attempt to explain the nature of gravity in terms of the laws of electromagnetism. He published the theory in 1929. The ideas he put forward conflicted with the emerging understanding of quantum mechanics, which put him at odds with much of the physics community at large, and led to his famous falling out with fellow Nobel winner Niels Bohr. Although he continued to work on the Unified Field Theory for the rest of his life, Einstein was never able to satisfactorily master the problem, and it remains unsolved to this day.
The auctioned letter reveals Einstein as both an accomplished physicist and a caring father, making it an extraordinary historic document.
The one page letter in German, signed “Papa,” reads: “Your letter made me very happy, particularly your comment regarding the hotel. Just like you, I hate it and it is with delight that I am detecting here a deep inner kinship between us, which I treasure. It seems to me it has been so long since I have seen you and I am longing to have you around me once again.
“For Easter, Albert and his wife will be visiting here. You could be coming at the same time, no matter. I would make sure you have sleeping quarters at a friend’s house while Albert is here. By the way, there is still another hurdle. On the 14th of March I have to flee to escape from my 50th Birthday Party otherwise I would run the risk of perhaps getting seasick. But there is still a lot of time until Easter. At any rate, I certainly want to see you before you graduate from High School.
“I am now very happy because I finally solved to my total satisfaction, after immensely intensive work, my gravitation-electricity problem. This, in a way, concludes my life’s work—the remainder simply is bonus material. Remarkably, how through all this strenuous work I made it in good shape and am feeling quite well. I do, however, practically live the life of a recluse and follow a frugal way of live. When we see each other again, I shall try to explain to you and describe this lifestyle a bit. In no way do I expect your approval and perhaps desire to join this guild. I could not care less.
“Don’t get overwhelmed by that heavy volume of a book I sent you. One should read it in small segments, always keeping in mind that this represents chosen selections of intellectual work through the centuries, expressed by an unimportant, but decent and clear thinking human being.”
Einstein added a PS: “I have been reading with great admiration Bernard Shaw’s new book on Socialism and Capitalism. I will be sending it to you soon and strongly recommend you definitely read this remarkable book.”
Online bidding for the document began on September 27 and will conclude on October 12. Other offerings in the same auction: Albert Einstein’s letter to the widow of NY Dr. Isidore W. Held, who helped Jewish intellectuals escape from Nazi Germany; an Albert Einstein typed letter from WW2, in which he pledged “my influence” to a would-be Jewish refugee; and a vintage glossy press photo of Einstein in a candid moment, signed in the lower border.
