Marie Jean Herault De Sechelles, a French revolutionist, born in Paris in 1760, guillotined there, April 5, 1794. He was a lawyer, and was advocate general at the Chatelet. When the revolution broke out he embraced its principles with ardor, and distinguished himself by personal bravery at the siege of the Bastile. In September, 1791, he was elected by the city of Paris to the legislative assembly, where he at once joined the extreme left. Having been returned to the convention by the department of Seine-et-Oise, he was chosen president of that body, Nov. 2, 1792. He was one of the commissioners sent to organize the department of Mont Blanc, and while absent from Paris on this mission signed a letter voting for the "condemnation" of the king, after the words "to death " had been stricken from it at the request of one of his colleagues, the abbe Gregoire. He joined Danton and Lacroix in demanding the trial of Henriot, and presided at the well known sitting of June 2, 1793, when he proclaimed the proscription of the Girondists. On June 10 he presented a report from the committee of public safety on the proposed constitution, which had been drawn up mainly by himself, but it was not accepted.

He also presided at the great fete of Aug. 10, 1793. He was an uncompromising democrat, and as member of the committee of public safety proposed many measures of great severity. When sent on a mission to Alsace in September, 1793, he wrote: "I have planted guillotines on my route, and find that they have produced good effects." The consideration he enjoyed provoked the jealousy of Robespierre, and on a frivolous pretext he was imprisoned. On March 31, 1794, St. Just accused him in the convention of being a noble by birth and of having protected the emigres. He was condemned to death with Danton, Desmoulins, and others, and met his fate with calmness. He was the author of many works, among which were Visite a Buffon (Paris, 1785), and The-orie de l'ambition (1802), written during his last imprisonment.
