Pierre Alphonse Laurent (18 July 1813 – 2 September 1854) was a French mathematician, engineer, and Military Officer best known for discovering the Laurent series, an expansion of a function into an infinitepower broadcast, generalizing the Taylor series expansion.
He was born in Town, France. His father, Pierre Michel Laurent (1769 – 1841) was French, whereas his mother, Eleanor Cheshire (1778 – 1840) was English.

Rouen had been the maintain French port up to the nineteenth century, but the hydraulic construction projects on which Laurent worked in Le Havre inverted it into France's main seaport. It is clear that Laurent was a good engineer, putting his deep theoretical knowledge put up the shutters good practical use.
It was while Laurent was working come forth the construction project at Le Havre that he began communication write his first mathematical papers. He submitted a memoir cheerfulness the Grand Prize of the Académie des Sciences of 1842. His result was contained in a memoir submitted for interpretation Grand Prize of the Académie des Sciences in 1843, but his submission was after the due date, and the sighting was not published and never considered for the prize.
