Sophie Germain (1776-1831) was a French mathematician, physicist, and philosopher. She is best known for her work on number theory and elasticity, and for her correspondence with Carl Friedrich Gauss.
Germain was born in Paris, France, on April 1, 1776. She was the daughter of Ambroise-Marie Germain, a wealthy merchant, and Marie-Madeline Gruguel. Germain showed an early aptitude for mathematics, and she began studying the subject in secret at the age of 13.
In 1794, Germain was inspired by the story of Archimedes' death to begin studying mathematics seriously. She read through the works of Leonhard Euler and Joseph-Louis Lagrange, and she began to write her own mathematical papers.
In 1803, Germain submitted her first paper to the French Academy of Sciences. The paper was on the theory of numbers, and it was rejected by the Academy because Germain was a woman.

Germain was undeterred by the Academy's rejection, and she continued to submit papers to the Academy under a male pseudonym. In 1808, she won the Academy's Grand Prix for her work on the theory of elasticity.
In 1816, Germain began a correspondence with Carl Friedrich Gauss. The two mathematicians exchanged letters for several years, and they discussed a wide range of mathematical topics.
Germain died in Paris on June 27, 1831. She was 55 years old.
Germain's work on number theory and elasticity was groundbreaking, and she is considered to be one of the most important mathematicians of the 19th century. She was also a pioneer for women in mathematics, and she helped to pave the way for future generations of female mathematicians.

Here are some of Sophie Germain's most important contributions to mathematics:

She proved the Sophie Germain prime conjecture, which is an important step in the proof of Fermat's last theorem.
She made significant contributions to the theory of elasticity, including the development of the Navier-Germain equations.
She was the first woman to win the Grand Prix of the French Academy of Sciences.

Germain's work was not without its challenges. She faced discrimination because she was a woman, and she was often forced to publish her work under a male pseudonym. However, she persevered and made significant contributions to mathematics.
Germain's legacy is one of brilliance and perseverance. She is an inspiration to mathematicians of all ages, and her work continues to have a major impact on the field of mathematics.
