Early Life, Family and Training

Katarzyna Kobro was born on 26 January 1898 in Moscow, Russian Empire. Her upbringing was shaped by a multicultural household, rooted in the different identities of her parents. Her father, Nikolai Alexander Michael von Kobro, was a Baltic German from present-day Latvia, while her mother, Evgenia Rozanov, was Russian. These early years were spent in Riga, before the family moved to Moscow in 1915.

The years following the move to Moscow were defined by formal study. From 1917 to 1920, Katarzyna Kobro attended the Moscow School of Painting, Sculpture and Architecture. It was during this period of training that she began to develop the technical foundations of her practice. She was a member of the Moscow Union of Artists during these formative years, moving through a landscape of significant artistic shifts in the city.

Life and Activity in Poland

After marrying Władysław Strzemiński in 1920, she moved to Poland in 1922. By 1924, she had obtained Polish citizenship. Her presence in the country was marked by a steady involvement in the local avant-garde. In 1926, she became a co-founder of the Praesens Group, working alongside Bohdan Lachert and Szymon Syrkus. This period of collaboration lasted until 1929, when she left the group.

Later, she helped form the a.r. group, also known as the Revolutionary Artists or Real Avant-Garde. This collective included Władysław Strzemiński, Henryk Stażewski, Jan Brzękowski, and Julian Przyboś. Beyond these circles, her efforts were directed toward the institutional side of art, as she was instrumental in the establishment of the Museum of Art in Łódź.

Technique and Style

Her work moves away from the personal and the emotional. She sought an absolute objectivism of form, stripping away the traces of individualism and subjectivism that often cling to a creator's hand. As a prominent representative of the Constructivist movement in Poland, her approach was rooted in the integration of spatial rhythm and scientific principles. She did not look for beauty in the traditional sense, rejecting Aestheticism in favor of a logic that governed how objects occupy a room.

She treated sculpture as a way to organize space rather than a solid mass to be looked at. This concept of Spatiality relied on the use of prefabricated elements and man-made products, often working with wood and metal to achieve a precise, industrial quality. Her pieces were not meant to be isolated objects but were designed to exist in a calculated relationship with their surroundings. By using these materials, she explored how a multi-dimensional abstract form could interact with the air and the light around it.

Key Works and Artistic Contributions

Her hands worked with wood and metal to create spatial objects that sought to find a rhythm within the air around them. In about 1924, she produced Abstract Sculpture 3, a piece that began her exploration of how form occupies a room. By 1931, her focus on the relationship between time and space became more structured, a concept she explored through the creation of Spatial Composition No. 6. This period of her life was marked by a deep interest in the mathematical and scientific aspects of perception, leading her to co-author the essay "Composing space: calculating space-time rhythms" in 1931.

The way she approached the physical presence of an object continued to evolve through the decades. In 1937, she added her signature to the 1936 Dimensionist Manifesto, aligning her practice with new ways of seeing the world. Her later work moved toward different forms of expression, such as the Standing Female Nude from 1948. These pieces show a life spent testing the limits of how a shape can exist within a space, moving from the strictness of early abstraction toward a more varied engagement with the human form.
