Person: Arbogast, Louis François Antoine
Louis Arbogast was a French mathematician who worked on the calculus of derivatives and the operational calculus.
Mathematical Profile (Excerpt):
 From this time on information on Arbogast becomes more plentiful.
 While at the Collège de Colmar Arbogast entered a mathematical competition which was run by the St Petersburg Academy.
 Arbogast submitted an essay to the St Petersburg Academy in which he came down firmly on the side of Euler.
 Arbogast won the prize with his essay and his notion of discontinuous function became important in Cauchy's more rigorous approach to analysis.
 In 1789 Arbogast moved from Colmar to Strasbourg where he taught mathematics at the École d'Artillerie.
 Arbogast's career in Strasbourg reached new heights.
 The formal algebraic manipulation of series investigated by Lagrange and Laplace in the 1770s was put in the form of operator equalities by Arbogast in 1800 in Calcul des dérivations.
 Arbogast was interested in the history of mathematics and classified Mersenne's papers and collected manuscript copies of memoirs and letters of Fermat, Descartes, Johann Bernoulli, Varignon, de L'Hôpital and others.
 Arbogast was friendly with François Français and together they worked on the calculus of derivations and the operational calculus.
 After Arbogast died in 1803, François Français inherited his collection of manuscripts, and also his mathematical papers.
 He continued Arbogast's work on the operational calculus and presented a memoir on this topic, in particular applying the methods to study projectiles in a resistant medium, to the Académie des Sciences in 1804.
 The historical manuscripts which went to François Français on Arbogast's death were bought by Libri from a bookseller in Metz in 1839.
 We should mention one other important contribution made by Arbogast.
 Arbogast was elected to the Académie des Sciences in 1792 and the mathematics section of the Institut National in 1796.
Born 4 October 1759, Mutzig, Alsace. Died 18 April 1803, Strasbourg, France.
