A real hero in finance died today. Jack Bogle, founder of Vanguard Group, created an investment juggernaut that now has over $5 trillion in assets. He created a company with a unique structure in the investment industry in that the owners of Vanguard mutual funds are the owners of the company. Instead of accumulating billions in wealth, this structure meant investors would be the ones that benefited as Vanguard consistently drove down the cost of their funds leaving more for investors. Here's what Warren Buffett had to say upon Jack's passing: "He did more for American investors as a whole than any individual I have known." What an example of servant leadership. He left the world a better place. 

Here are just one of the many tributes rolling in The Worth of A Man: A Tribute To Jack Bogle (Forbes).
