Edouard Manet

Édouard Manet (23 January 1832 – 30 April 1883) was a French painter. One of the first 19th-century artists to approach modern and postmodern-life subjects, he was a pivotal figure in the transition from Realism to Impressionism.
His early masterworks, The Luncheon on the Grass (Le déjeuner sur l'herbe) and Olympia, engendered great controversy and served as rallying points for the young painters who would create Impressionism. Today, these are considered watershed paintings that mark the genesis of modern art. [Source]
