He considered himself to be a modern painter, at that time, although his early work is in line with the Amsterdam Impressionists and is influenced by Vincent van Gogh, both in style and subject matter.
It made him realize there was a higher, more spiritual level in painting that originates from the mind rather than from everyday life, and that abstraction is the only logical outcome of this.
127, on 9 November 1912, because "The mimetic expression of velocity (whatever its form may be: the aeroplane, the automobile, and so on) is diametrically opposed to the character of painting, the supreme origin of which is to be found in inner life".
[6] It was while reviewing an exhibition for one of these magazines he wrote for, in 1915 (halfway through his two-year service in the army), that he came in contact with the works of Piet Mondrian, who was eight years older than he was, and had by then already gained some attention with his paintings.
Doesburg then installed himself near to the Bauhaus buildings and started to attract school students interested in the new ideas of Constructivism, Dadaism, and De Stijl.
Because the two men got to see each other on a much more regular basis the differences in character became apparent: Mondrian was an introvert, while van Doesburg was more flamboyant and extravagant.
In recent years, however, this theory has been challenged by art historians such as Carel Blotkamp, who cites the artist's different concepts about space and time.
After the split, Van Doesburg launched a new concept for his art, Elementarism,[9] which was characterized by the diagonal lines and which rivaled Mondrian's Neo-Plasticism.
Together with El Lissitzky and Kurt Schwitters, Van Doesburg pioneered the efforts to an International of Arts in two congresses held in Düsseldorf and Weimar, in 1922.
[11] Van Doesburg also kept a link with Dada, publishing the magazine Mécano under the heteronym of I. K. Bonset (possibly derived from "Ik ben zot", Dutch for "I am foolish").
Under a second pseudonym, Aldo Camini, he published anti-philosophical prose, inspired by the Italian representative of Metaphysical art, Carlo Carrà.
For example, his Space-time construction #3 (1923) was a key work in the Miller Company Collection of Abstract Art's Painting toward architecture exhibition (1947–52, 28 venues).
