In 1930, Dutch artist Theo Van Doesburg and four of his friends openly declared war on every kind of impressionism, sensibility and subjectivity in art. The concrete art group and the magazine Art Concret, which they founded in Paris, argued for rational, universal art “entirely conceived and shaped by the mind”, without “receiving anything from nature's formal properties, or from sensuality or sentimentality”1.
Heir to Mondrian’s neoplasticism and to the principles promoted by the De Stijl movement, concrete art sought “absolute clarity” through a “simple, visually controllable” structure that signified nothing beyond itself. The emotional impulses perceptible in traditional abstraction were excluded in favour of a logical composition based on predetermined mathematical principles.
Concrete art’s Zurich home crystallised a few years later when Max Bill (1908-1994)—influenced by his studies at the Bauhaus and his friendship with members of the Abstraction-Création group in Paris—drew up his own theory on concrete art. Bill advocated a rational art, developed according to its own rules and integrating everyday life. Like the artists of the Allianz association, which Bill joined in 1937, he favoured the use of neutral, geometric, easily understandable shapes.
These Zurich concrete artists—including Richard Paul Lohse (1902-1988), Leo Leuppi, Walter Bodmer, Verena Loewensberg, Camille Graeser (1892-1980), Gottfried Honegger (1917-2016) and Sophie Tauber-Arp—all showed the same predilection for skilfully calculated geometric arrangements. In that vein, Lohse opted for modular compositions in which all elements are mutually supportive, independent and equal; Graeser favoured systematic composition principles like addition, rotation or progression, while Honegger ended up entrusting the production of mathematical calculations to a computer. The visual effect is that of an almost rhythmic chromatic polyphony, which seems to be articulated—as in the works of Fritz Glarner (1899-1972)—according to warm/cool, bright/dark and neutral/intense relationships.
For the artists of concrete art, the work primarily designates a balanced, coherent whole, whose elements are defined by their relationships with one another within the image. These relationships very often become symbols of an ideal, democratic organization, based on all individuals benefiting from the same rights and freedoms.
