‘Unmatched’: contents of 70s French power couple’s final bolthole up for auction

Sotheby's to sell designs and artwork of Francois Catroux, decorator to the stars, and his wife, Betty, muse to Yves Saint Laurent

In 1970s Paris, Betty Catroux and her husband, Francois, were the glittering couple at the heart of French high society and what used to be known as the international jet set.

She was the androgynous model and darling of the French designer Yves Saint Laurent, he the self-taught interior decorator who transformed the mansions, grand apartments and chateaux of the super-rich or royal, among them the Rothschilds, Diane von Furstenberg and, later, Roman Abramovich.
