Who was M.H.J. Schoenmaekers and how did his ideas influence Piet Mondrian?

M.H.J. Schoenmaekers was a theosophical philosopher whom Piet Mondrian met in Laren, Netherlands, around 1914. His work focused on the symbolic meaning of lines and the mathematical construction of the universe.1

Schoenmaekers’ ideas had a decisive influence on Mondrian’s artistic vision, providing him with a distinct set of graphic rules that aligned with his own developing formal vocabulary. While Mondrian had long sought to use his art as a site for spiritual awakening, Schoenmaekers’ theories offered a concrete framework to achieve this goal of merging art and life. These concepts helped push Mondrian’s style toward total abstraction, encouraging him to move beyond the limitations of Cubism and toward the use of vertical and horizontal lines to express a harmonious, universal order. This philosophical foundation became central to the development of De Stijl and Mondrian's mature style, which he later termed Neoplasticism.12
