He was born in Saint-Omer in France on 24 March 1809.[3][4] His parents were Claude-Joseph Liouville (an army officer) and Thérèse Liouville (née Balland).

Liouville gained admission to the

École des Ponts et Chaussées after graduating from the Polytechnique, but opted instead for a career in mathematics. After some years as an assistant at various institutions including the École Centrale Paris, he was appointed as professor at the École Polytechnique in 1838. He obtained a chair in mathematics at the Collège de France
in 1850 and a chair in mechanics at the Faculté des Sciences in 1857.

Besides his academic achievements, he was very talented in organisational matters. Liouville founded the

Constituting Assembly
in 1848. However, after his defeat in the legislative elections in 1849, he turned away from politics.

Liouville worked in a number of different fields in mathematics, including

Riemann-Liouville integral to consider differentiation and integration of a fractional order
.

In 1851, he was elected a foreign member of the Royal Swedish Academy of Sciences. In 1853, he was elected as a member of the American Philosophical Society.[6]

The crater Liouville on the Moon is named after him. So is the Liouville function, an important function in number theory.
