Sol LeWitt (1928-2007)

"If the artist carried through his idea and makes it into visible form, then all the steps in the process are of importance. The idea itself, even if not made visual, is as much a work of art as any finished product." (S. LeWitt, 'Paragraphs on Conceptual Art', Artforum Vol.5, no. 10, Summer 1967, pp. 79-83).
