✉Up for Auction: Einstein Letters Detailing General Relativity and Grand Unified Theory.
Einstein wrote the two letters to his friend and scientific sounding board Michele Besso. One letter outlines Einstein’s early thoughts on a grand unified theory, while the other, written much later, is a bit more philosophical, asking what can be known and whether some physical theories can ever be proved.
The bidding for each letter starts at $60,000. Sam Heller, a spokesman for the auction house, said the letters came from a private collection, whose owner didn’t want to be identified.
The Nate Sanders auction house has sold other Einstein memorabilia, Heller said. In August, the firm sold a 1938 letter from Einstein to Besso lamenting the agreement British Prime Minister Neville Chamberlain signed with Germany for $31,250, and an autographed copy of a famous photo of Einstein sticking out his tongue sold for $125,000 in July.
