Background and Early Life

Katarzyna Kobro, born Katarzyna Kosovo, was born on January 26, 1898 in Latvia. Her family was of Polish ancestry. As a child, Kobro’s family moved frequently before settling in Moscow in 1910. As a teenager, Kobro began her studies at the School of Painting, Sculpture and Architecture in Moscow. There she met and began a relationship with the Polish sculptor Władysław Strzemiński.

In 1917, Kobro and Strzemiński moved to Smolensk together. They married in 1920 and adopted the joint surname Kobro-Strzemiński. Though they never formally divorced, the two began living separately in 1931. After leaving Smolensk in 1918, Kobro-Strzemiński moved to Moscow where Kobro attended the Second State Free Art Studios.

Early Sculptural Work

Kobro began working professionally as a sculptor in Moscow. Her early work from the 1910s to early 1920s consisted mainly of figural sculptures. Stylistically, these early pieces blended influences from Cubism, Futurism, and Russian Constructivism. She created simplified, abstracted human forms, experimenting with geometric shapes and negative space.

In 1920, she exhibited her work for the first time at an exhibition in Moscow. That same year, she and Strzemiński moved to Poland and settled in Łódź. This move marked a major turning point in Kobro’s shift towards complete abstraction.

The Polish Avant-Garde

In Poland during the 1920s, Kobro joined the group of avant-garde artists centered in Łódź and Warsaw. This vibrant artistic community included Strzemiński as well as artists like Henryk Stażewski, Henryk Berlewi, and Mieczysław Szczuka.

Together, they launched the group and artistic movement a.r. (Revolutionary Artists) in 1929. The group promoted abstract art and launched an eponymous journal to spread their ideas. Their artistic aim was to apply abstract geometrical forms and mathematics to art in order create utopian universal art.

Within this community of Polish avant-garde artists, Kobro stood out as a pioneering woman artist adopting abstract style early on. She was a central force shaping the aesthetics and ideology of the Polish avant-garde together with Strzemiński.

Mature Sculptural Style

In the late 1920s, Kobro’s style reached maturity as she transitioned fully into nonrepresentational abstract sculpture. By this point she worked almost exclusively in steel, creating geometric, machinelike sculptures.

Kobro believed sculpture should reflect the modern, industrial world. She wanted to use modern materials like steel to capture the dynamism and rhythm of contemporary life. To achieve this, Kobro composed her sculptures from simple planar and cylindrical forms arranged in space. Her sculptures focus on the relationship between forms, space, and time rather than realistic representation.

Her most well-known works were part of her “Space Compositions” series created between 1929-1937. These sculptures balance vertical and horizontal elements on pyramidal bases. Kobro used identical modules or units in varying arrangements to experiment with form, space, and rhythm. Examples from this seminal series include Kompozycja Przestrzenna (Spatial Composition) 1929-1930, and Kompozycja Przestrzenna 6 (Spatial Composition 6) 1930.

Wartime and Posthumous Recognition

In 1937, Kobro was forced to stop working as an artist due to financial pressures. Much of her work was destroyed or ruined in World War II. Only 18 known sculptures survived. In 1957, Kobro died in Łódź.

Though she was recognized within avant-garde circles during her lifetime, Kobro’s work remained relatively obscure for decades after. Her contributions became better known through reconstructed sculptures and renewed scholarly interest beginning around the 1970s. Major exhibitions of her work took place internationally at venues like the Museum of Modern Art in New York.

Today, she is regarded as a key pioneer of European abstract sculpture and an important woman modernist. As evidence of her growing recognition, in 2022 Google commemorated Kobro’s 124th birthday with a Google Doodle spotlighting her work. She leaves behind an influential if modest oeuvre that helped shape abstraction and avant-garde art in interwar Poland.

Notable Sculptures and Artworks

Here is an overview of some of Katarzyna Kobro’s most important sculptures:

  • Kompozycja przestrzenna (Spatial Composition), 1929-1930: An angular, machine-like sculpture balancing geometric steel forms on a pyramidal base. Her first abstract, nonrepresentational sculpture.
  • Kompozycja przestrzenna 2 (Spatial Composition 2), 1929-1930: Resembles an abstract human figure with vertical and horizontal rods. Blends influences from Russian Constructivists like Tatlin.
  • Kompozycja przestrzenna 4 (Spatial Composition 4), 1931: A pyramidal arrangement of rectangular steel rods and circular forms. Exemplifies her modular, geometric style.
  • W przestrzeni (In Space), 1931: Suspended mobile sculpture with rotating cylinders and intersecting circular forms. Explores space and time through movement.
  • Kompozycja przestrzenna 6 (Spatial Composition 6), c. 1930: Considered her most famous work, with vertically stacked rectangular forms. Epitomizes her “Space Compositions” series.
  • Kompozycja przestrzenna 7 (Spatial Composition 7), c. 1931: Abstract sculpture of vertically oriented steel rods on a triangular base. Continues her experiments with form and space.

Kobro’s Artistic Legacy

Despite the limited number of Kobro’s extant works, her artistic impact and key contributions include:

  • Pioneering avant-garde abstract sculpture in the 1920s before many of her European peers.
  • Helping develop the aesthetics and ideology of the Polish avant-garde alongside figures like Strzemiński.
  • Using modern industrial materials like steel and glass to reflect the 20th century urban experience.
  • Focusing on space, time, and the relationship between forms over realistic representation.
  • Influencing generations of artists involved in op art, kinetic art, and Constructivist movements after World War II.
  • Proving that abstract art could have complexity, meaning, and emotional resonance.
  • Overcoming gender barriers as an innovative woman artist during the interwar period.
  • Leaving behind an influential if small oeuvre that remains powerful in its simplicity and symbolism.

Though many works were lost, Kobro’s legacy continues to be felt as scholarship and exhibitions bring wider recognition to her innovations in form, space, and the avant-garde.
