surrealism - marcel duchamp

Rrose Sélavy, or Rose Sélavy, was one of the pseudonyms of artist Marcel Duchamp. The name, a pun, sounds like the French phrase "Eros, c'est la vie", which translates to English as "Eros, that's life". It has also been read as "arroser la vie" ("to make a toast to life").
marcel and rrose both did their own art work and were 'different characters' even though it was the same person.
Sélavy emerged in 1921 in a series of photographs by Man Ray of Duchamp dressed as a woman. Through the 1920s, Man Ray and Duchamp collaborated on more photos of Sélavy. Duchamp later used the name as the byline on written material and signed several creations with it.

Fountain is a 1917 work widely attributed to Marcel Duchamp. The scandalous work was a porcelain urinal, which was signed "R.Mutt" and titled Fountain. Submitted for the exhibition of the Society of Independent Artists in 1917, Fountain was rejected by the committee, even though the rules stated that all works would be accepted from artists who paid the fee.

Fountain is the result of a collaboration. In a 1917 letter to his sister, Duchamp himself credits a female friend with the idea, as he writes to Suzanne Duchamp: "One of my female friends who had adopted the pseudonym Richard Mutt sent me a porcelain urinal as a sculpture."^[5] Duchamp never identified his collaborator, but two candidates have been proposed as collaborators. First, the Dadaist Baroness Elsa von Freytag-Loringhoven, whose scatological aesthetics are more in line with the choice of a urinal as art than Duchamp's;^[6] and second, Louise Norton, who contributed an essay to The Blind Man discussingFountain.

i really like the idea that they did this as a type of rebellion
