 After his death, Jacques-Philippe-Augustin Douchet and Nicolas Beauzée, who were both teachers at the École royale militaire, took over his work.Born in Marseille, Dumarsais trained in Paris as a lawyer, before abandoning the bar to pursue the life of the mind, subsisting on occasional law students and later on the meager revenue from a "pension" in the city's Faubourg-Saint Victor.He wrote clandestine tracts in favour of freethought, attacked the French church in books and pamphlets, and proposed, to no avail, a reform of French orthography.
