Albert Einstein thought he had made the breakthrough of his career and wrote a letter to his son sharing the news. It turned out not to be so. But in his letter, the physicist took a rare moment to reflect on his life’s work and offered a glimpse into his fond relationship with his son.
The one-page handwritten letter is being auctioned this week by Boston’s RR Auction. It could fetch more than $100,000 US, company officials said.
In the letter, which is estimated to be from 1929, Einstein tells his son, Eduard Einstein, that he has made a major discovery.
“I am now very happy because I finally solved to my total satisfaction, after immensely intensive work, my gravitation-electricity problem,” he wrote, according to a translation of the German letter. “This, in a way, concludes my life’s work — the remainder simply is bonus material.”
