Marie Ennemond Camille Jordan (French:[ʒɔʁdɑ̃]; 5 January 1838 – 22 January 1922) was a French mathematician, known both for his foundational work ingroup theory and for his influentialCours d'analyse.
Jordan was born inLyon and educated at theÉcole polytechnique. He was an engineer by profession; later in life he taught at the École polytechnique and theCollège de France, where he had a reputation for eccentric choices of notation.
He is remembered now by name in a number of results:
Jordan's work did much to bringGalois theory into the mainstream. He also investigated theMathieu groups, the first examples ofsporadic groups. HisTraité des substitutions, onpermutation groups, was published in 1870; this treatise won for Jordan the 1870prix Poncelet.[1] He was an Invited Speaker of theICM in 1920 inStrasbourg.[2]
Theasteroid25593 Camillejordan andInstitut Camille Jordan [fr] are named in his honour.
Camille Jordan is not to be confused with thegeodesistWilhelm Jordan (Gauss–Jordan elimination) or the physicistPascual Jordan (Jordan algebras).
