John Bogle is an American investor and the founder of the Vanguard Group. He is known for his contributions to the field of finance, particularly his advocacy for index investing and his criticism of the mutual fund industry.

Bogle is widely credited with pioneering the concept of index investing, which involves creating portfolios that track a broad market index, such as the S&P 500, rather than trying to beat the market through active stock picking.

He has received numerous awards and accolades for his work, and he is widely respected as a leader in the field of finance.
