Phil was a founder of one of the country’s first mutual funds and a legendary investor who swapped investment ideas with Warren Buffett’s father Howard Buffett half a century ago. For 55 years, Phil was manager of the Pioneer Fund, a mutual fund he founded in 1928. He pioneered the concept of value investing, introducing it four years before the publication of Security Analysis by Benjamin Graham and David Dodd. Warren Buffett said Phil established “the best long-term investment record of anyone in America.” Dan is pictured here at age 19.
