Jean-Jacques Regis de Cambacères (1753-1824) was a French politician whose career had begun in law. Shortly before the 1789 Revolution, he became the secretary representing the gentry, but was soon to change sides with the advent of the Revolution as he was a republican at heart. In 1792 he was elected député à la convention and he prepared the case against Louis XVI during the King's trial. He then became president of the comité du salut public, promoting peace between Spain and Russia.
Under Napoléon, Cambacères was given a life appointment as archéchancelier of the Senate, was created Duke of Parma and was awarded numerous decorations. He resided in the hôtel de Roquelaure, which was entirely furnished with pieces presented by Napoleon in 1807. He remained a loyal republican and died in Paris at the age of 71, after having been exiled in Belgium.
