John Bogle, formerly the head of Vanguard, is famous among investors. Just how famous? Ask Taylor Larimore, Mel Lindauer and Michael LeBoeuf, authors of The Bogleheads' Guide to Investing. The trio took Bogle's philosophy on investing and reduced it to a short and poignant slogan: invest smart, safe and cheap, and you'll do well, according to Reuters.
Bogle is a household name in the mutual fund industry. He fathered the first index fund, the Vanguard 500, and has been sharply critical of high fund fees.
