Marcel Duchamp (28 July 1887 – 2 October 1968) was a French artist whose work is most often associated with the Dadaist and Surrealist movements. Considered by some to be one of the most important artists of the 20th century, Duchamp's output influenced the development of post-World War I Western art. He advised modern art collectors, such as Peggy Guggenheim and other prominent figures, thereby helping to shape the tastes of Western art during this period

Jacques-Louis David  (30 August 1748 – 29 December 1825) was an influential French painter in the Neoclassical style, considered to be the preeminent painter of the era. In the 1780s his cerebral brand of history painting marked a change in taste away from Rococo frivolity toward a classical austerity and severity, heightened feeling chiming with the moral climate of the final years of the Ancien Régime.
