All humans endure their private struggles, but rarely do we know what troubles our most famous public figures until now. In her recent book, Andy Warhol was a Hoarder: Inside the Mind of History’s Great Personalities (National Geographic, 2016), award-winning journalist Claudia Kalb shares her research into the mental health histories of several well-known and much-loved people. She discusses Princess Diana’s struggle with eating disorder and severe loneliness; the impact of Frank Lloyd Wrights narcissism on his architectural masterpieces and personal relationships; and Andy Warhol’s penchant for holding onto and storing decades’ worth of day-to-day objects. In our interview, Kalb talks about her keen interest in these people and their stories, and we discuss the way such stories humanize these idealized figures and universalize the human quest for mental and emotional well-being. Claudia Kalb is an award-winning journalist who specializes in the fields of medicine, health, and science, former senior writer at Newsweek, and contributor to publications such as Smithsonian and Scientific American.
