Edward J. Dolman, chairman of Christie’s International, is leaving the auction house to join the board of the Qatar Museums Authority.

A Christie’s employee for 27 years, Dolman will be working directly for the emir’s daughter, Mayassa Bint Hamad Al Thani, as the executive director of her office, the London-based auction house said today in an e-mailed statement.

Dolman, 51, became chairman of Christie’s in September 2010, when Steven Murphy, the former president and chief executive of the U.S.-based publishing company Rodale Inc., succeeded him as CEO.

Dolman had been appointed CEO in December 1999 after spending several years as a European furniture specialist.

Qatar’s museums authority administers collections of Islamic art, Orientalist paintings, natural history, photography, armor, Islamic coins, costumes and jewelry.

In October 2010, the emir said he may be interested in acquiring the London-based auction house, the Financial Times reported, after months of speculation about a possible Qatari bid. Christie’s remains a private company owned by the French billionaire Francois Pinault. The auction house was bought by his holding company, Groupe Artemis SA, for $1.2 billion in May 1998.

Active Buyers

The new National Museum of Qatar, designed by Jean Nouvel, is scheduled to open in December 2014, according to the authority’s website. Members of the Qatari royal family have been active buyers of Western modern and contemporary art in recent years.
