French painter, theorist, writer, critic and poet, who along with Albert Gleizes, developed the theoretical foundations of Cubism. His earliest works, from 1900 to 1904, were influenced by the Neo-impressionism of Georges Seurat and Henri-Edmond Cross. Between 1904 and 1907 Metzinger worked in the Divisionist and Fauvist styles with a strong Cézannian component, leading to some of the first proto-Cubist works.
