In the four short years since she founded her eponymous Savile Row gallery, Pilar Ordovas, 43, has quietly risen to the top tier of London power dealers, going head-to-head with her former mentor and employer Larry Gagosian. The Madrid native has become known for original, tightly focused exhibitions that plumb unexplored facets of an artist’s work. Recent triumphs include a grouping of the 1950s sculpture of Alberto Giacometti and David Smith and a show exploring the relationship between Joan Miró and Spanish sculptor Eduardo Chillida. This fall, she is presenting “The Big Blue,” a collection of sea-inspired works assembled by Damien Hirst, who seems to be taking well to his new role as curator. “The Big Blue,” runs September 25 through December 12; 25 Savile Row; 44-20/7287-5013; ordovasart.com.
