Leon Chwistek

Leon Chwistek (Kraków, Austria-Hungary, 13 June 1884 – Barvikha near Moscow, Russia, 20 August 1944) was a Polish logician, philosopher, mathematician, avant-garde painter, theoretician of modern art and literary critic.

[1] Starting in 1929, Chwistek was a Professor of Logic at the University of Lwów in a position for which Alfred Tarski had also applied.

After the outbreak of World War II and the occupation of Lwów (renamed to Lviv) by the USSR, he remained at the university.

Chwistek's fellow artist and closest friend, Stanislaw Ignacy Witkiewicz, harshly criticized his philosophical views.

In his 1919 painting titled Fencing inspirations from avant-garde trends prior to World War I such as cubism, Italian futurism, and Robert Delaunay’s simultanism can be observed.
