Sotheby’s Launches ‘Luxury & Lifestyle’ Division
It brings the jewelry, watches, wine, cars and experiences categories, as well as the relationship with Sotheby’s International Realty, under one umbrella.
New York--To start off 2017, Sotheby’s has announced that it’s undergoing a slight reorganization of its product categories.
The auction house is launching a new Luxury & Lifestyle division, bringing the jewelry, watches, wine, cars and experiences categories, as well as the relationship with Sotheby’s International Realty, under one umbrella.
Sotheby’s did not respond to questions about the “experiences” division by press time.
The auction house has tapped one of its current executives, Maarten ten Holder, to head this new division, effective immediately.
He will relocate to New York from London, where he most recently served as the managing director of Sotheby’s operations in Europe, the Middle East, India and Africa.
Prior to his post in London, he held leadership positions at Sotheby’s in New York, Milan and Amsterdam.
Ten Holder started his career at Sotheby’s Amsterdam and helped organize the auction house’s first auction in France in 1999.
He took on the role of deputy managing director of Sotheby’s Italy in 2002 before moving to New York four years later to be the managing director for North and South America.
While he was in New York, and more recently London, ten Holder oversaw some very high-profile auctions, including the sale of Edvard Munch’s “The Scream,” the collection of “Bunny” Mellon, property from the personal collection of Deborah, Duchess of Devonshire, and the personal collection of David Bowie.
He also was involved in a number of major jewelry sales, like the collections of Mrs. Charles Wrightsman, and Estée Lauder and Evelyn H. Lauder.
In 2005, he started working with car auctions at Sotheby’s sale of cars and related memorabilia at Ferrari’s museum in Maranello, Italy.
Ten Holder regularly conducts sales in all of Sotheby’s major international selling locations in five languages.
