John C. Bogle

John Clifton "Jack" Bogle (May 8, 1929 – January 16, 2019) was an American investor, business magnate and philanthropist. He was the founder and chief executive of The Vanguard Group and is credited with popularizing the index fund. An avid investor and money manager himself, he preached investment over speculation, long-term patience over short-term action and reducing broker fees as much as possible. An ideal investment vehicle for Bogle was a low-cost index fund representing the entire US market, held over a lifetime with dividends reinvested.

His 1999 book ''Common Sense on Mutual Funds: New Imperatives for the Intelligent Investor'' became a bestseller and is considered a classic within the investment community. Provided by Wikipedia
