Tad Smith

Sotheby’s has appointed Charles F Stewart as chief executive officer. Joining from communications and media company Altice USA, he takes over from Tad Smith who has served as CEO since 2015.

The competition between auction houses to expand their private sales operations took a new twist with the announcement last week that Sotheby’s had bought art advisory firm Art Agency, Partners (AAP).

Sotheby’s latest set of results give the first indication of how Tad Smith will direct the company.

Sotheby’s have appointed Tad Smith, aged 49, as president and chief executive officer, effective March 31, 2015.
