Didier Grumbach is one of the most discreet, yet powerful and prestigious figures in the world of fashion. In 1966, he co-founded Saint-Laurent Rive Gauche with Yves Saint-Laurent and Pierre Bergé. Between 1968 and 1973, he worked alongside Hubert de Givenchy in Givenchy Nouvelle Boutique. In 1971, Grumbach created the company Créateurs & Industriels, in order to bridge the gap between designers and the industry: in that context, he featured the first shows of designers such as Jean-Paul Gaultier, Issey Miyake and Jean-Charles de Castelbajac. He discovered Thierry Mugler's talent very early on, and, in 1978, founded and became the chairman of the company that bears the designer's name. He then served as chairman of Yves Saint Laurent, Inc. In 1985, he joined the staff of the Institut Français de la Mode, where he served as Director of Studies, and then as Dean of the Professorial Staff. In 1998, he was elected chairman of the Fédération Française de la Couture, du Prêt-à-Porter des Couturiers et des Créateurs de Mode, and of the Chambre Syndicale de la Haute Couture. His book, Histoires de la Mode, first published in French in 1993, and updated in 2008 and 2014, has been translated into numerous languages, including Chinese, Portuguese and Romanian.
