R-26 was an artistic salon regularly held at the private residence of socialites Madeleine, Marie-Jacques and Robert Perrier at 26 Rue Norvins in the Montmartre district of Paris. First convened on 1 January 1930, the salon became a meeting ground for many creative luminaries of the next eighty years, including singer Josephine Baker, architect Le Corbusier and musician Django Reinhardt.
