Nomenclature
Philippe Gustave Doulcet, Comte De Pontécoulant (1795-1874) was a French mathematician and astronomer. In 1829 he used the mathematical methods of Poisson and Lagrange to successfully predicted the return of Halley's comet with good precision. His prediction of the perihelion passage was correct to within two days.
