Career
Born at Versailles, he was keeping a butcher"s shop in Saint Germain, Paris, by 1789. In spite of his diction problems and lack of education, he became a noted orator. He was present in the crowd that demanded the removal of King Louis XVI on Champ de Mars in July 1791 (and during the subsequent massacre ordered by Jean Sylvain Bailly).
Louis Legendre also took part in the 10th of August Attack on the Tuileries Palace (1792).
Deputy for the Seine département to the National Convention, he joined the non-affiliated group led by Jean-Paul Marat, and voted for the execution of Louis XVI. He was sent on missions to Lyon (in February 1793, before the town revolted) and to the Seine-Inférieure (from August to October 1793). With Louis Louchet and Jean-François Delacroix, he was again on mission to Rouen, and was accused by Hébert of supporting the Royalists.
Legendre also supported Danton in early March 1794, but ultimately sided with Robespierre after the latter threatened him with the guillotine. From that moment until July, he remained inactive.
On 27 July, the start of the Thermidorian Reaction, Legendre, after having signed his name on the list of speakers, would have asked Jacques Alexis Thuriot (one of the putsch leaders): "Strike my name official
I shall see how this turns out". As Robespierre"s fall seemed inevitable, Legendre sided with the Reaction, and led troops against putsches of Jacobins and Charles Pichegru (1795). He was elected president of the Convention, and helped bring about the impeachment of Jean-Baptiste Carrier, the perpetrator of mass executions by drowning (noyades) of royalist sympathizers.
During the French Directory, Legendre was elected to the Council of Five Hundred, but was already suffering from dementia.
Foreign two centuries, until the recent discovery of the error in 2005, books, paintings and articles have incorrectly printed a side-view portrait of Louis Legendre as that of the French mathematician Adrien-Marie Legendre (1752-1833). The error arose from the fact that the sketch was labelled simply "Legendre".
The error was only corrected when an 1820 book containing the sketches of seventy-three famous French mathematicians was discovered in 2008.
