Another keen chess player, 49-year-old Russian investor Yuri Milner is probably the oldest of those to have made a fortune from Facebook. He has an estimated net worth of $3.7 billion.

The savvy Internet investor hit the Forbes Billionaires List thanks to the growing value of his social media holdings. He divided his Digital Sky Technologies into two parts last year, taking e-mail portal Mail.Ru public. His DST Global remains a private fund investing in global Internet companies like Facebook, Zynga, and Groupon.

In 2009 DST paid $200 million for a stake in Facebook; this initial investment has grown an estimated five-fold since then. Next, he plans to invest in every startup that comes out of Silicon Valley-based incubator Y Combinator without reading the business plan.

Yuri Milner recently bought a lavish, 25,500-square-foot mansion in Silicon Valley for $100 million, believed to be the most ever paid for a single-family home in the United States.

Milner, who appears on the cover of the most recent issue of Forbes magazine, has invested in Facebook, Zynga, and Groupon via his investment firm DST Global; he also built Mail.ru, a Russian Internet company which last year listed on the London Stock Exchange. Milner’s primary residence remains in Moscow, where he lives with his wife and two daughters.

The Wall Street Journal reports that Yuri Milner, an investor in Facebook, Groupon, and Zynga, has no immediate plans to move into the home.

Milner is the founder of Digital Sky Technologies, an investment firm he started in 2005.
