Peter Thiel is a technology mogul, an investor, a lawyer and a libertarian-leaning Republican. He believes in creating underwater colonies and has sunk millions into research of life-extending technologies. And he’s Ron Paul’s biggest supporter — at least monetarily.
Thiel (pronounced “teal”) contributed $2.6 million to the pro-Paul super PAC Endorse Liberty . His donation comprised nearly all the group's funds, and Endorse Liberty all but disappeared once Thiel cut off funding when it became clear Paul wouldn't win the GOP presidential nomination. The large donations drew comparisons to Sheldon Adelson  and Foster Friess , who gave generously to super PACs backing Newt Gingrich and Rick Santorum. But unlike Gingrich and Santorum, Paul has never met his patron, according to Slate .
Thiel made his fortune as the founder and CEO of PayPal, taking the company public and selling it to eBay in 2002 for $1.5 billion (Thiel later contributed more than $25,000 to then-CEO Meg Whitman’s 2010 California gubernatorial run). He was an early investor in Facebook, fronting $500,000 and — until recently — owned 2.5 percent of the company. Thiel sold 16.8 million of his shares in May, when Facebook went public, and an additional 20 million shares in August, pocketing a combined $1 billion, CNN Money reported. 
Some of Thiel’s other ventures haven’t been quite as successful. The assets of Clarium Capital Management, the hedge fund he founded, shrunk from their peak of $7 billion in mid-2008 to less than $1 billion in mid-2011 — a loss of about 90 percent, Bloomberg reported .
But Thiel is one to take the long view. At a speech he gave  in Washington, D.C., in February 2012, Thiel said of his donations to Paul, “The campaign really is for 2016. I think we're just trying to build a libertarian base for the next cycle.”
Editor's Note: We have amended this profile to include those details relevant to Mr. Thiel's background.
