The Art Newspaper reports that Cheyenne Westphal has left Sotheby’s:

Westphal, who joined Sotheby’s in 1990, has overseen every major contemporary art sale in Europe since 1999. Dubbed “Sotheby’s secret weapon” by Harper’s Bazaar, Westphal helped orchestrate the unprecedented 2008 Damien Hirst auction, Beautiful Inside My Head Forever, which fetched £121m. She also won over Count Duerckheim to negotiate the sale of his collection of postwar German art in 2011, which raised a record £62m. “I was the first person outside the family to see the collection. He simply said, ‘You do what you do best.’ And he was thrilled with the results,” Westphal said at the time.
