About Pierre-Simon Girard

  • Pierre-Simon Girard (4 November 1765 – 30 November 1836) was a French mathematician and engineer, who worked on fluid mechanics. Girard was born in Caen.
  • A prodigy who invented a water turbine at the age of ten, he worked as an engineer at the École Nationale des Ponts et ChaussĂ©es.
  • He was in charge of planning and construction of the Amiens canal and the Ourcq canal.
  • He collaborated with Gaspard de Prony on the Dictionnaire des Ponts et ChaussĂ©es (Dictionary of Bridges and Highways, 1787).
  • He wrote on fluids, and in 1798 he published a monograph, TraitĂ© analytique de la rĂ©sistance des solides on beam theory, including possibly its first history, within the topic of strength of materials.
  • The complicated beam equations were not of practical much use, since he applied Euler's non-linear theory.
  • In 1799 he led a cultural and scientific expedition to Upper Egypt.
  • He died in Paris, aged 71.
