ENSCI was founded in 1982 under the sponsorship of Jean Prouvé and Charlotte Perriand, and has been established in the same building that once housed the Ateliers Saint-Sabin of the Maison Jansen, hence its name. The École nationale supérieure de création industrielle (ENSCI) is a French design school located in the 11th arrondissement of Paris. As a public commercial and industrial establishment under authority of both the Ministry of Culture and the Ministry of Industry, it is the first and only French national institute exclusively devoted to the advanced studies in design. It is a member of the Hautes Études-Sorbonne-Arts et Métiers cluster and of the Conférence des grandes écoles. The premises are open 24 hours a day and seven days a week, enabling students to work according to their own production schedules and patterns. It has been classed number one design school in the Americas & Europe region by the 2011 Red Dot Award: Design Concept ranking, and the best design school in France by the 2012 L'Étudiant ranking. It is also one of the 60 best design schools in the world according to the 2007 Businessweek D-Schools list.
