March 16 (Reuters) - Auction house Sotheby's appointed Madison Square Garden Co Chief Executive Tad Smith its CEO, replacing William Ruprecht.
Sotheby's said in November that Ruprecht would step down once a successor was found.
The company also said on Monday that it had separated the roles of chairman and CEO, naming lead independent director Domenico De Sole chairman.
