John Bogle, a longtime advocate for investors’ rights, founded Vanguard in 1974 and helped build it into a giant asset manager that today handles $4.9 trillion, making it second in size only to BlackRock. He had esophageal cancer, his assistant told the NYT. Mr. Bogle stepped down as chief executive of Vanguard in 1996 and as its chairman at the end of 1999. Last year, his net worth was estimated at $80 million — far less than many of his peers. John C.
