A lot of them coming in today.
John C. BogleFounder of the trillion-dollar Vanguard Group dies at 89
Born into a family that lost everything to the Great Depression, he secured a scholarship to an elite private academy at the end of World War II and parlayed that into attendance at Princeton University. In 1975, after botching a merger at his previous employer, he founded the Vanguard Group. Built on a model of client ownership, the company eventually ballooned to a $5 trillion value. Because of the structure of the company, Bogle himself had a net worth of about 0.002% of that, less than $100 million.
He preached a very conservative, broad-based, "buy-and-hold" approach to investing and saving. He is credited with inventing the "index fund" that follows particular stock indexes, as well as for lowering the cost of overhead required to invest in the stock market.
Beleaguered by health problems his entire life, including a heart attack at age 31, Bogle received a heart transplant at 65. He died at age 89.
