If you were to make a list of who you believe are the most controversial artists in history, the name of Marcel Duchamp would be topping many of the lists. He was a French painter, sculptor, writer and a master chess player whose work is often associated with Dadaism and branches of conceptual art, although he does not really seem to fully fit with neither of the two. Duchamp is considered by many to be responsible for the 20th century’s change in perception of what art is and how art is made. We believe it’s appropriate to start this biography by quoting Marcel himself: You cannot define electricity. The same can be said of art. It is a kind of inner current in a human being, or something which needs no definition.
