Where did Yuri Milner get all that money that he gave away to 9 lucky physicists? Wired has an account.
The story appears to be that he is a very successful investor, especially in Silicon valley. It's a bit short of detail in some interesting spots. One excerpt:
The message seems clear: Milner may have invested in virtually every social media powerhouse, from Facebook to Twitter to Spotify. He might be the vanguard of an entirely new financial philosophy. He might be the most controversial money guy in Silicon Valley—sought after, feared, and derided in more or less equal measure. But at heart he is just a nice Jewish boy.
And it seems he has a Macaroni factory back in Russia.
