About Étienne Bobillier
- Étienne Bobillier (17 April 1798 – 22 March 1840) was a French mathematician. He was born in Lons-le-Saunier, France.
- At the age of 19 he was accepted into the École Polytechnique and studied there for a year.
- However, due to a shortage of money, in 1818 he became an instructor in mathematics at the École des Arts et Métiers in Châlons-sur-Marne.
- In 1829, he was sent to Angers to be director of studies.
- The following year he served in the national guard during the 1830 revolution.
- In 1832 he returned to Châlons after his post was abolished, and was promoted to professor. In 1836 he began suffering from health problems, but continued teaching; declining to take a leave to recuperate.
- As a result, he died in Châlons at the relatively early age of 41. He is noted for his work on geometry, particularly the algebraic treatment of geometric surfaces and the polars of curves.
- He also worked on statics and the catenary. The crater Bobillier on the Moon is named after him.
