Einsteins theory of happiness sold for $1.5m

The Nobel Prize-winning German-born physicist gave the notes to a courier in Tokyo in 1922 instead of a tip.

Instead, he handed the messenger a signed note - using stationary of the Imperial Hotel Tokyo - with one sentence, written in German: "A calm and humble life will bring more happiness than the pursuit of success and the constant restlessness that comes with it."

A second note written at the same time simply reads: "Where there's a will, there's a way." It sold for $240,000, Winner's auction house said.

It said the buyer of one of the notes was a European who wished to remain anonymous.
The seller is reported to be the nephew of the messenger.
