Camille Jordan
Camille Jordan (
January 5 1838 -
January 22 1921) was a
French mathematician, known both for his foundational work in
group theory and for his influential
Cours d'analyse. He was born in
Lyons and educated at the
Ecole Polytechnique. He was an engineer by profession; later in life he taught at the Ecole Polytechnique and the
College de France; where he had a reputation for eccentric choices of notation.
He is remembered now by name in a number of foundational results:
In fact the work of Jordan did much to bring
Galois theory into the mainstream. He also investigated the Mathieu groups, the first examples of sporadic groups. His
Traité des substitutions, on permutation groups, was published in
1870.
