Carl Einstein (Neuwied, Germany, 1895 - Lestelle-Betharram, France, 1940) is probably the least classical art historians of the twentieth century. Einstein was one of the most relevant and multifaceted personalities of the twentieth century artistic avant-garde. His books, articles and essays were key pieces to the critical study of the avant-garde and the fostering of the study and promotion of art history in the past century. Einstein worked as a novelist, poet, playwright, essayist, art and literature critic as well as the author of a screenplay. However, it is in the field of art history that he is found to be among the most interesting innovators; Apollinaire said he had "one of the most perceptive minds." In his numerous texts he gave expression to the introduction of African art in the West, or the approval of Cubism as a full movement.
