Prominent in Paris in the 1960s, Daniel Buren is internationally recognized for his contribution to Conceptual Art as a founding member of the BMPT group (comprised of Buren, Olivier Mosset, Michel Parmentier, and Niele Toroni), in which he abandoned the idea of painting as object and dismissed the importance of authorship. Pasting pre-fabricated, alternating white and colored vertical stripes on unconventional supports and space—ranging from doorways to billboards to the courtyard of the Palais Royal in Paris—he challenged conventional notions of where art can be seen and how it can be understood.
