Which Cubist painter developed the style known as 'Tubism'?

Fernand Léger developed the Cubist style known as “Tubism.”

Léger’s early Cubist paintings transformed people, trees and machines into sturdy cylindrical, tubular and spherical forms. Critics, especially Louis Vauxcelles, used “Tubism” around 1911 as a sometimes mocking description of this distinctive approach. Léger’s Nudes in the Forest, painted around 1909–1910, is a key example.

His version of Cubism differed from the muted, fragmented compositions associated with Pablo Picasso and Georges Braque. Léger used emphatic volumes, strong outlines and increasingly vivid contrasts, giving his pictures a mechanical, dynamic character. The forms appear assembled like parts of a machine rather than dissolved into delicate facets.

“Tubism” was not a formal movement with a large organized membership; it was chiefly a label for Léger’s personal interpretation of Cubism. He later moved toward more figurative and populist imagery, but the cylindrical forms of his early work remained central to his reputation. The term can also cause confusion because “tubism” has been used separately for a paint-application technique associated with Georges Mathieu.
