The career of Alma Johanna Ruubel reached a significant milestone in 1929, when she became the first female lecturer in mathematics at the University of Tartu. Her academic trajectory spanned seven decades of Estonian history, shifting from early pedagogical training in Viljandi to establishing new research directions in curvilinear representational geometry during her long tenure in higher education.
Early Education and Academic Entry
Born in 1899 in the Õisu Rural Municipality, Ruubel completed her initial schooling at the Viljandi Estonian Educational Society's girls' school by 1916. Amidst the instability of World War I and the German occupation of 1918, she joined a student group to maintain her educational progress. By 1919, she had finished her secondary studies and begun attending teacher preparation courses at the University of Tartu. Her professional life as an educator started that same year with a position at the Pärnu Commercial School.

Ruubel officially enrolled at the University of Tartu in 1926. Her potential was recognized by Professor Gerhard Rägo, who appointed her as an assistant at the Institute of Mathematics during her third year of study. She graduated cum laude in 1932. Influenced by Rägo, she explored numerical integration methods derived from John Couch Adams and Richard von Mises, eventually earning a master's degree in 1936. Her 1946 recertification of this research led to the formal awarding of a Ph.D. in Physics and Mathematics.
Contributions to Geometry
Appointed as an associate professor in 1949, Ruubel taught a diverse range of subjects including probability theory, theoretical mechanics, and various forms of geometry. In 1952, she moved to the Estonian Academy of Agriculture to lead the department of visual geometry. Her primary research focus was the creation of curvilinear representational geometry, which she documented in works such as "Orthogonal circular projection" in 1958 and "Generalized axonometry" in 1967. She continued lecturing and organizing methodological work until 1973.
