"It was an all-time record for an auction of a document in Israel", Winner's spokesman Meni Chadad told AFP.
Einstein gave the two hand-written memos in German to a Japanese messenger in lieu of a tip while he was staying at the Imperial Hotel, shortly after he was informed by telegram he would be awarded the 1921 Nobel Prize in physics for his services to theoretical physics.
Einstein's note about his theory of happiness exceeded the pre-auction estimate of between $5,000 and $8,000.
It is reported that in November 1922, the great physicist, who came from lectures in Japan, recently learned about the awarding of the Nobel prize and paginasexo the first fruits of worldwide fame, was not at hand change for a tip.
Impressed and a little embarrassed by the publicity he received, the scientist tried to write his thoughts and feelings on a paper while holed up at the Imperial Hotel in Tokyo.
Gal Wiener, CEO of the auction house, said the auction for the note began at $2,000 and bids quickly flooded in for about 25 minutes. It was bought by a European who wished to remain anonymous.More news: Iraq's Kurds offer to freeze results of independence vote

A second note written by Einstein at the same time on a blank piece of paper that simply reads "where there's a will, there's a way" was sold at a price of 240,000 USA dollars, said the auction. The courier either refused to accept a tip, in line with local practice, or Einstein had no small change available.
Instead, Einstein wrote two short notes and handed it to the messenger.
The note eventually fetched $1.56 million.
Roni Grosz, an Einstein archivist at Jerusalem's Hebrew University, said: "What we're doing here is painting the portrait of Einstein - the man, the scientist, his effect on the world - through his writings".
Einstein served as a non-resident governor of Jerusalem's Hebrew University.
Einstein died in 1955.
