For T’s design issue, I traveled to Sent, Switzerland, a remote alpine community 40 miles northeast of St. Moritz, to meet the Italian dealer Gian Enzo Sperone and his partner, the Sicilian artist Tania Pistone, at their 11,000-square-foot, three-story home, where they store a lifetime of art — along with little reminders of the people who’ve supported him along the way, and the ones he’s helped too: the flyer for his 1965 show of Andy Warhol’s screen prints in Turin; a photograph of Julian Schnabel dedicated by the artist to “G.E.S.”; the funeral program for the American painter and AIDS activist Frank Moore, who died in 2002. Now in his 80s, Sperone, who is often credited with bringing American Pop Art to Italy in the 1960s, and who would later boost the careers of such Neo-Expressionist painters as Francesco Clemente and Schnabel at Sperone Westwater, the New York gallery he opened in 1975 with Angela Westwater and Konrad Fischer, doesn’t travel much anymore. At dinner, he mentioned Luis Buñuel’s 1962 film, “The Exterminating Angel,” one of his favorites, about a group of wealthy guests who find themselves unable to leave a party. “It was a tragedy in the end,” he says. “But in my case, it’s not that bad. Every day, I stay here, walking around, watching the mountain.” 📸 Ricardo Labougle
