Dorothea Rockburne

Dorothea Rockburne (born 1932, Verdun, Quebec) is a Canadian-American artist whose practice from the late 1960s onwards developed a rigorous engagement with mathematics, set theory and the intrinsic properties of materials. Studying at Black Mountain College in the early 1950s — where she encountered John Cage, Merce Cunningham and Franz Kline — Rockburne developed an approach to art-making grounded in structural logic rather than expressive gesture.

Her works of the late 1960s and 1970s used folded paper, chipboard, crude oil and carbon paper to produce works in which the material itself determined the form. The Drawing Which Makes Itself series (1972–73) and the Locus series applied set theory directly to the organisation of paper on wall and floor, producing works of austere geometric precision. Later series, including Egyptian Paintings and works inspired by Renaissance geometry and astronomy, extended this mathematical rigour into colour and light.

Rockburne’s participation in Photonotations (Rosa Esman Gallery, 1976) reflects her engagement with photography as a medium for conceptual investigation during a period when the boundaries between drawing, sculpture and documentation were actively being tested. Her work is held in major collections including the Museum of Modern Art, New York, and the Whitney Museum of American Art.
