Sophie germain life history

Marie Sophie Germain was born on 1st april 1776. She was born to a very rich silk merchant of the paris ambroise francois. Later her father became a director of a bank. Marie’s mother’s name was Marie Madeline. When Marie first met maths she was 13 years old.

Marie’s fascination towards maths was a bothering thing for her family. Because it was like a taboo for that time’s society. Germain started working on number theory in 1798. After reading Carl Fredriech Gauss’s work she renewed her work on number theory. In 1809 she began to work on elasticity theory.

She worked on it for three years and submitted her research papers in 1811. She is also known for working on Fermat’s theorem. Later in her life she continued her work on maths and physics.

In 1829 she learned that she had breast cancer. She worked until her death in 1831. In 1831 before her death her works on elasticity theory were published in a journal.

Sophie’s contribution in mathematics

Her chief interest was number theory. She shared her work’s details with other great mathematicians like Gauss and Legendre. Later she published her work on Fermat’s theorem proving that n = p -1. Then she worked on the vibrating elastic surface of the metal plates due to her interest in elasticity. The equation for elasticity proposed by Marie was this.
