What is the core concept behind Oskar Hansen’s theory of Open Form?

Creating a backdrop for human actions

Grzegorz Kowalski: Sculptor of Space and Emotion

Grzegorz Kowalski, born January 10, 1942 in Warsaw, Poland, stands as a pivotal figure in Polish sculpture and artistic thought. His career began under the tutelage of Oskar Hansen and Jerzy Jarnuszkiewicz at the Academy of Fine Arts in Warsaw—institutions that championed the revolutionary “Open Form” theory—a concept profoundly shaping his artistic vision and pedagogical approach. This formative influence instilled in him a belief in the transformative potential of art, alongside an unwavering commitment to intellectual rigor and critical engagement with societal dynamics.

Early Influences: Hansen’s Open Form challenged conventional sculptural conventions, advocating for spatial forms that serve as “background” for human actions—a paradigm shift mirroring Jarnuszkiewicz's emphasis on collaborative artistic endeavors.
Avant-Garde Symposia & Biennial Explorations: Kowalski actively participated in groundbreaking symposiums and biennials during the 1960s and ’70s, immersing himself in dialogues with fellow artists and scientists—events that fueled his exploration of new materials and techniques.
The Repassage Gallery Years (1972-1980): His association with Repassage Gallery provided a fertile ground for experimentation and artistic freedom amidst the constraints of communist censorship, fostering a distinctive style characterized by dynamic environments and audiovisual performances.

His sculptural output reflects this intellectual fervor—primarily consisting of abstract metal sculptures that prioritize geometric precision alongside poetic resonance. Kowalski’s exploration of spatial relationships aligns seamlessly with Hansen's theoretical framework, where sculpture isn’t merely an object but a conduit for conveying complex ideas and emotions. He consistently sought to engage viewers actively within his artworks, mirroring the collaborative spirit championed by Jarnuszkiewicz—a pedagogical ethos that continues to permeate “Kowalnia” Studio today.

Notable Works: Among Kowalski’s most celebrated pieces are “Manipulative Composition,” presented at São Paulo Biennial in 1969, and “Sundial,” erected during the Olympic Games in Mexico City—monuments that embody his commitment to monumental scale and conceptual innovation.
“Kowalnia” Studio: Founded in 1985, Kowalski’s studio became a crucible for fostering critical art discourse and nurturing emerging talent—a legacy cemented by its enduring connection to the avant-garde tradition and its unwavering dedication to humanist values.

Throughout his artistic journey, Kowalski confronted ideological pressures and championed intellectual autonomy—experiences that solidified his conviction in the importance of questioning established norms and embracing unconventional perspectives. As he eloquently articulated: “If until '68 one would attempt to establish some form of cooperation within the framework of this regime, simply in order to live and to do something positive... Some form of cooperation was accepted... After '68, there were no illusions left – this was a system that could not be reformed in any way, it had to be rejected”. This formative encounter propelled him toward a path of dissent—a stance reflected in his unwavering advocacy for artistic freedom and intellectual integrity. Grzegorz Kowalski continues to inspire artists worldwide with his pioneering approach to sculpture and his steadfast commitment to fostering critical dialogue within the realm of visual arts.
