California-based auction house Profiles in History has sold 27 letters of Albert Einstein for $420,000 at an auction on Thursday. An anonymous individual has acquired a letter explaining the theory of relativity and Japan’s atomic bombings for $62,500, which Einstein wrote to his son in 1945.
The letters known as Einstein letters reveal a wide array of information, including a toy engine given by his uncle, and how it inspired his passion for science. Topics like the status of his son’s geometry class, parenting style and thoughts on god was also included. Some of the letters were in German, and the rest was in English. The man who has acquired these letters has chosen to remain anonymous.
Joseph Maddalena, founder of profiles in history said that these 27 letters offered a rare and interesting glimpse of Einstein’s thoughts outside scientific words. They also revealed Einstein’s other personality and events. The auction prices of the letters ranged from $6,875 to $62,500. The two letters about thoughts on god, written in 1940 were sold for $28,125 and $34,375 respectively.
Historically significant documents like 13th Amendment to the Constitution was sold for $187,500. The amendment was signed by 125 members of the US congress in 1865, which ended slavery in the U.S. Einstein’s theory of general relativity talks about the laws of physics that are same for all non-accelerating observers, and the speed of light in a vacuum was independent of all observers. The theory of special relativity was explained in 1905.
Einstein spent over a decade to include acceleration in the theory and published his theory of general relativity in 1915. He came to the conclusion that massive objects caused a distortion in space-time, which was felt as gravity. Maddalena added that the latter were collected by a seller over the years, and were purchased by various individuals.
