John Berry III, Berry’s father, confirmed his death Thursday afternoon to Rolling Stone. He said his son suffered from frontal lobe dementia, which had worsened in recent months.
Berry is credited with coming up with the name Beastie Boys when they were teenagers. He attended the Walden School in New York with Mike Diamond. The group formed in July 1981, with Berry and Diamond joined by Adam Yauch and Kate Schellenbach. The first Beastie Boys shows took place at Berry's old loft at the corner of West 100th Street and Broadway in Manhattan’s Upper West Side, where a small crowd gathered to hear the fledgling hardcore/punk band.
