Early Life and Education
Jean Nicolas Pierre Hachette first went to college in Charleville. Later, he continued his studies in Reims. In 1788, he went back to Mézières. There, he worked at an engineering school. His job was to draw for the science teachers.
In 1793, Hachette became a professor of hydrography. This is the science of mapping and describing water bodies. He taught in the towns of Collioure and Port-Vendre. While teaching, he wrote several important papers. These papers used geometry to solve problems in navigation. He sent his work to Gaspard Monge, who was a government minister at the time. Monge was impressed and helped Hachette get a new job in Paris.
Teaching at a Famous School
In late 1794, a very important school called the École Polytechnique was created. Hachette was chosen to teach there. He worked with Gaspard Monge in the department of descriptive geometry. This is a type of geometry used to draw 3D objects on a 2D surface.
Hachette taught many bright students at this school. Some of them became very famous scientists themselves. These included Siméon Poisson, François Arago, and Augustin Jean Fresnel. Earlier that year, Hachette also joined an expedition with Guyton de Morveau. He was present when the French army entered Brussels after the Battle of Fleurus.
Challenges and Recognition
In 1816, there was a change in government in France. King Louis XVIII came to power. Because of this, Hachette was removed from his teaching job at the École Polytechnique. However, he continued to teach at another school, the École Normale. He had been a professor there since 1810 and kept that position until he died.
In 1823, Hachette was nominated to join the Académie des Sciences. This is a very respected group of scientists. But the king refused to approve his election. It wasn't until 1831, after another big change in government called the July Revolution, that he finally received this honor. Jean Nicolas Pierre Hachette passed away in Paris on January 16, 1834.
His Important Work
People greatly respected Hachette for his good character. They also admired his scientific achievements and his service to the public. His main work was in the field of descriptive geometry. He also applied this geometry to arts and mechanical engineering.
Hachette helped to further develop the ideas of Gaspard Monge in geometry. He played a big part in France's quick progress in building machinery. This happened soon after the École Polytechnique was established.
Key Publications
Here are some of Jean Nicolas Pierre Hachette's main books:
- Deux Suppléments à la Géométrie descriptive de Monge (1811 and 1818)
- Éléments de géométrie à trois dimensions (1817)
- Collection des épures de géométrie, etc. (1795 and 1817)
