Below is part of the result for the query "When did the first female mathematician"
Hypatia of Alexandria - (c. 350 – 415) was a Greek mathematician, astronomer, and philosopher in Egypt. She was the first well-documented woman in mathematics. She was the daughter of Theon of Alexandria, himself a mathematician and astronomer. Hypatia taught mathematics and philosophy at the Alexandrian Museum, and her students included men and women. She was also a prolific writer, and her works included commentaries on the works of Euclid, Ptolemy, and Archimedes. Hypatia was killed by a mob of Christian zealots in 415.
Here are some other notable female mathematicians:
Maria Gaetana Agnesi (1718–1799) - Italian mathematician, philosopher, theologian, and humanitarian. She is best known for her book "Lezioni di Arithmetica, Geometria, Algebra, Trigonometria, e Analisi Infinita" (Lessons in Arithmetic, Geometry, Algebra, Trigonometry, and Infinite Analysis), which was one of the first textbooks on mathematical analysis.
