Pierre-Henri Hugoniot (born in Allenjoie, Doubs, France on 5 June 1851; died in Nantes, France in February 1887)[1] was an inventor, mathematician, and physicist who worked on fluid mechanics, especially on issues related to material shock.
He was promoted to captain in January 1884, and in April was appointed assistant professor of mechanical engineering at the École polytechnique.
He conducted, along with his colleague Hippolyte Sébert (1839-1930), research on the trigger gas accompanying the detonation of a cannon.
He invented the theory based on conservation of mass, momentum, and energy, which allowed for improvements in fluid flow studies (with applications to aerospace).
