"He earned degrees from Harvard University and MIT and then skipped through the ranks at investment bank Morgan Stanley, becoming chief financial officer in 1994, when he was 36. Hedge fund phenom Julian Robertson hired him four years later as chief operating officer at Tiger Management LLC.
Duff struck out on his own in 2000, founding hedge fund firm FrontPoint Partners LLC -- which Duff, a lifelong outdoorsman, named for a mountain-climbing technique used to scale steep ice faces with crampons. Six years later, he sold the company to Morgan Stanley for $400 million. source"
