Sotheby’s has named Helena Newman—the auction house’s Co-Head Worldwide of Impressionist and Modern Art—chairman of Sotheby’s Europe. Newman will join fellow chairs Oliver Barker, Mario Tavella, and Philipp Württemberg. Newman, who has been with Sotheby’s for twenty-eight years, oversaw the highest grossing auction ever held in Europe, which netted $263 million in 2010. Newman’s appointment follows a string of high-profile departures at Sotheby’s, including Henry Wyndham, who stepped down as chairman of Sotheby’s Europe in February.
