While Sophie was restricted to her home due to the danger resulting from the revolts in Paris she spent time in her father’s library After stumbling across a book about the legend of Archimedes death, who was speared to death because of his love for math, Sophie’s interest in the subject began.

5. Who Was Sophie Germain? She began to teach herself mathematics in her father’s library This interest was inappropriate for females during this time and her parents did many things to deter her and make studying difficult

6. Who Was Sophie Germain? In addition, because of her social location (middle class) it was also inappropriate for her to casually learn math for that was reserved for aristocratic women Despite her parents disapproval and societal discrimination, she did not give up and initially studied differential calculus without a tutor

7. Who Was Sophie Germain? In 1794 the Ecole Polytechnique was founded in Paris to train mathematicians and scientists At the time, Sophie was 18 and because she was a woman she was not allowed to enroll Somehow she was able to get the lecture notes from several math courses taught by prominent mathematicians and studied from them

8. Who Was Sophie Germain? Sophie had a special interest in the teachings of a mathematician, J. L. Lagrange One day she submitted a mathematical analysis paper to him using a name of one of his former male students

9. Who Was Sophie Germain? Lagrange was so impressed with the paper he read and wanted to meet the student who wrote it He was even more impressed after discovering the author was female Lagrange recognized her abilities, offered to be her mentor and became her entry point in the male-dominated realm of math and science
