René-François Dumas  René-François Dumas, born 14 December 1753 in Jussey, in the bailiwick of Amont (now in Haute-Saône), was a revolutionary French lawyer and politician, regarded as a "Robespierrist", who died on 28 July 1794 (10 Thermidor) at Paris. René-François, despite his ferocity, was born of respectable parents, and well educated. In June 1790 Dumas founded a popular society in Lons-le-Saunier and became a member of the city council. In 1791 he was the mayor of Lons-le-Saunier. He became member of the "Society of the Friends of the Constitution", where he played a leading role, even occupying the presidency. On 26 September, 1793, Dumas was appointed vice-president of the Revolutionary Tribunal and involved in the trial of Madame Roland, Marie-Antoinette and Madame du Barry. On 8 April 1794, three days after the execution of Danton and Desmoulins, he became the president of the court, in lieu of Martial Joseph Armand Herman, who was appointed Foreign minister. In this quality, with Fouquier-Tinville as the public prosecutor, he headed several major political trials in which defendants were sentenced to death. The trial of the "first conspiracy of the prisons" on 13 April considered in particular the general Arthur Dillon, the archbishop constitutional of Paris Jean-Baptiste Gobel, procureur syndic of the Commune of Paris Pierre Gaspard Chaumette, and the widows Marie Marguerite Françoise Hébert and Lucile Desmoulins. In June the tribunal put in force the Law of 22 Prairial. According to Adolphe Thiers their goal was to keep the prisons empty. According to Fouquier-Tinville, Dumas and Coffinhal, the vice-president of the tribunal, went each morning to see Robespierre and did what he told them to do, not what the Committee of Public Safety had decided. His last victim was the Princess of Monaco on 28 July. At four o'clock in the afternoon a charge of 45 convicts was sent to the guillotine on the Place de la Nation, but was stopped on the way in the Faubourg Saint-Antoine. Francois Henriot, general of the Parisian National Guard, accompanied the procession.
