Numerous tributes to Vanguard founder Jack Bogle have praised his significant contribution to the fund industry and shareholders. Some accounts offered personal insights, such as a Wall Street Journal writer who recalled Bogle’s physical and intellectual energy, flexibility and a stubbornness which may have driven him to create the first index fund and a mutual fund company owned by its investors. Bogle’s philosophy and his belief in low-cost investing are well documented but his personal struggles with illness, including a heart transplant, may be less well known. The WSJ also highlighted the major ways Bogle revolutionized the industry, including championing low cost investments, urging investors to hold their investments for the long haul, and giving passive funds and ETFs increasing sway over U.S. corporate boardrooms. Morningstar also weighed in on Bogle’s legacy with its writers exploring in detail Bogle’s philosophy and his willingness to motivate people from the lowest to the highest ranks.
