How'd he get so rich? In 1979, Nicholas co-founded (with John Abele) medical products company Boston Scientific, which is the leading maker of catheters, stents, balloons, and medical devices that allow for less invasive surgery. Nicholas, a graduate of Duke University and the Fuqua School of Business, is today nonexecutive chairman of the firm.
