Inventor of the first retail index fund, advocate for investors, and relentless promoter of simple and low-cost investing, Bogle changed the fund industry. As Morningstar's Dan Culloton and Alec Lucas noted in their commentary shortly after Bogle's death, "There was nothing passive about the father of passive investing." Remembrances poured out after Bogle's passing, including those from Morningstar's Russ Kinnel, John Rekenthaler, and Jeff Ptak--as well as other Morningstar researchers included in this video. We also assembled more than a decade's worth of video interviews that we've done with Jack. Jack is certainly missed; the investing world is a better place because of him.
