John Bogle was the Founder of The Vanguard Group and President of the Bogle Financial Markets Research Center. He is best known for revolutionalizing the mutual fund world by pioneering index investing, which allows investors to buy mutual funds that track the broader market. One of his countless pioneering achievements was low-cost investing in mutual funds by creating no-load funds. As an avid investor and money manager, Bogle preached investment over-speculation, long-term patience over short-term action, and reduced broker fees.
