John Bogle, whose family’s struggles during the Great Depression led him to pioneer low-cost investing and to found Vanguard Group, now the world’s biggest mutual fund firm, died Jan. 16 at the age of 89, Vanguard said.
Bogle had been in frail health for years, surviving at least six heart attacks and receiving a heart transplant in 1996. The cause of death was cancer, according to Bogle’s assistant Michael Nolan.
