People talk of Pablo Picasso as the leader of the Cubists but, strictly speaking, he is no longer a Cubist. Today he is a Cubist, tomorrow he will be… - Marcel Duchamp

In 1913 I had the happy idea to fasten a bicycle wheel to a kitchen stool and watch it turn. A few months later I bought a cheap reproduction of a winter evening landscape, which I called 'Pharmacy' after assign two small dots, one red and one yellow, in the horizon. In New York in 1915 I bought at a hardware store an snow shovel on which I wrote 'In advance of the broken arm'. It was around that time that the word 'Readymade' came to mind to designate this form of manifestation.

I wanted to kill art for myself.. ..a new thought for that object.

First, there's the idea of the movement of the train [in his painting 'Nude (Study), Sad Young Man on a Train', (made in 1911–12)] and then that of the sad young man who is in a corridor and who is moving about; thus there are two parallel movements corresponding to each other. Then, there is the distortion of the young man—I had called this elementary parallelism. It was a formal decomposition; that is, linear elements following each other like parallels and distorting the object. The object is completely stretched out, as if elastic. The lines follow each other in parallels, while changing subtly to form the movement, or the form of the young man in question. I also used this procedure in the [painting] 'Nude Descending a Staircase'.
