In her article New Smithsonian exhibt shows Marcel Duhcamp's influance on Warhol, Jasper Johns,
Marsha Ducbrow defends the National Portrait Gallery's decision to show an exhibit about Marcel Duhamp, an artist not known for his portraits. She belives that while Duchamp did not actually make many portraits, he "revolutionized portraiture. And he greatly influenced artists including Andy Warhol, Jasper Johns, among other key 20th and 21st century artists whose works are included in 'Inventing Marcel Duchamp: The Dynamics of Portraiture' (March 27-August 2, 2009)." Duchamp was "a master of self-invention" who changed the concept of what a self-portrait or portrait could be. Duchamp had many alter-egos, such as Rrose Selevy and R. Mutt, as well as making influantial self-portraits, such as Belle haleine - Eau de voilette
While he did not produce many self-portraits,many of his works explored the concept of identity and defining the self, and thus he revolutionazed the art of portraiture and inspired future artists.
