Although his full surname was Barré de Saint-Venant in mathematical literature other than French he is known as Saint-Venant. He died in January in 1886 at Saint-Ouen, Loir-et-Cher.

Saint-Venant developed a vector calculus similar to that of Grassmann which he published in 1845. Graduating in 1816 he worked for the next 27 years as an engineer, initially his passion for chemistry led him a post as a élève-commissaire (student commissioner) for the Service des Poudres et Salpêtres (Powders and Saltpeter Service) and then as a civil engineer at the Corps des Ponts et Chaussées.

At age 86 he translated (with A Flamant)Clebsch's work on elasticity into French and published it as Théorie de l'élasticité des corps solidesⓉ and Saint-Venant added notes to the text which he wrote himself. In 1869 he was given the title 'Count' (comte) by Pope Pius IX.

    Grassmann had published his results in 1844, but Barré de Saint-Venant claimed he had developed the method in 1832. Even though he published before Stokes, the equations do not bear his name. Before him are William Kennedy Dickson (1860), Charles, Prince Napoléon (1950), Léon Brillouin (1889), Antoine Coysevox (1640), Peter Nolasco (1180), and Antoine, Duke of Lorraine (1489).

    He extended Navier's work on the bending of beams, publishing a full account in 1864. His father was Jean Barré de Saint-Venant, (1737–1810), a colonial officer of the Isle of Saint-Domingue (later Haiti).

Biography[edit]

Barré de Saint-Venant was born at the château de Fortoiseau, Villiers-en-Bière, Seine-et-Marne, France.

In 1871 he derived the equations for non-steady flow in open channels. His mother was Marie-Thérèse Josèphe Laborie (born Saint-Domingue, 1769). He then entered into a dispute with Grassmann about which of the two had thought of the ideas first. Although his full surname was Barré de Saint-Venant in mathematical literature other than French he is known as Saint-Venant.

Grassmann had published his results in 1844, but Barré de Saint-Venant claimed he had developed the method in 1832. Grassmann had published his results in 1844, but Saint-Venant claimed (and there is little reason to doubt him) that he had first developed these ideas in 1832. Note that Saint-Venant's co-translator A Flamant was a co-author of the obituary notice [3] for Saint-Venant.

    In 1843 he published the correct derivation of the Navier–Stokes equations for a viscous flow[2] and was the first to "properly identify the coefficient of viscosity and its role as a multiplying factor for the velocity gradients in the flow".
