Sofia became the first woman to be awarded a doctorate in mathematics.
On January 24, 1874, the University of Göttingen awarded Sofia Kovalevskaya a doctorate in mathematics, a monumental achievement considering the barriers women faced in academia. Her dissertation included original work on partial differential equations, which later became known as the Cauchy-Kovalevskaya theorem. This degree was conferred in absentia, marking a significant milestone as she became the first woman in the modern era to earn a doctorate in this field, laying the groundwork for future generations of women in mathematics.
