A note that Albert Einstein gave to a courier in Tokyo briefly describing his theory on happy living sold at auction in Jerusalem on Tuesday for $1.56 million, the auction house said.
During Einstein's trip to Japan in 1922 to receive the Nobel Prize in physics, he wrote notes on how to live a fulfilling life while staying at the Imperial Hotel in Tokyo. He also did not disclose who was the buyer and seller.
The winning bids for both notes were far higher than the pre-auction estimated price, the auctioneers said. The note was written during Einstein's 1922 visit to Japan after he was informed that he would be awarded the Nobel Prize in Physics.
One of the two signed notes said, "A calm and modest life brings more happiness than the pursuit of success combined with constant restlessness".
The note is one of two that were gifted to a Japanese courier at the hotel in lieu of a cash tip.
Instead, Einstein wrote two short notes and handed it to the messenger.
This is not all, Einstein's second note which read, "Where there's a will, there's a way", sold for more than $ 200,000.
The buyer was a European who wished to remain anonymous.
That's when the messenger arrived with a delivery and Einstein found himself without any money for a tip.
Almost 100 years later, the bellboy's nephew contacted the auction house in Israel to put the notes up for sale.
The seller is reported to be the nephew of the messenger.
He said: "What we're doing here is painting the portrait of Einstein - the man, the scientist, his effect on the world - through his writings". "This is a stone in the mosaic".
The auction comes after Einstein left his literary estate and personal papers in Israel after founding the Hebrew University in Jerusalem.
Albert Einstein's theories have changed our understanding of science, but his theory of happiness is his real million dollar idea.
