Pierre Alphonse Laurent

Pierre Alphonse Laurent ( born July 18, 1813 in Paris, † September 2, 1854 ) was a French mathematician.

Laurent worked as an engineer in the French army in the expansion of the port of Le Havre. His only known mathematical work was not published until after his death, although Augustin Louis Cauchy in 1843 reported on its contents in the French Academy. Subject of this work were convergence studies of the named after Laurent Laurent series. The studied in algebra Laurent polynomials are also named after him because of the obvious analogy to the Laurent series.

Pierre Alphonse Laurent is not to be confused with other French mathematicians that time, Hermann Laurent (1841-1908) and Pierre Laurent Wantzel ( 1814-1848 ).
