1. Charles-Pierre-Paul, Marquis de Savalette de Langes (1745-1797)
Savalette  de Langes was the son of Charles Pierre Savalette de  Magnanville  (1713-1790) – intendant of the Generality of Tours (1745)  and Keeper of  the Royal Treasury from 1756 to 1788 – and Marie-Émilie  Joly de Choin  (1726-1776), the daughter of a fermier général. In 1773,  like his  father, Savalette de Langes became a Keeper of the Royal  Treasury;  1790/91, Captain of the Paris National Guard in the battalion  of Saint  Roch and aide-de-campe to Marquis de Lafayette (1757-1834).

Gardes du Trésor royal (i.e. keeper of the royal treasury) was a heredity title. On the significance of the post, Roland Mousnier writes:
 The highest-ranking receveur-payeurs were the two gardes du Trésor royal.   According to the edict of June 1748 this office was worth 1,200,000   livres. They earned 5 percent of the official value of the office in   salary plus 12,000 additional livres when they were actually on duty;   they also received 1,500 livres in salary for their work on the council   and 60,000 livres, increased by Necker to 85,000, to cover the wages  and  expenses of their commis. These offices were family  property.  In 1749 Charles-Pierre Savalette de Magnanville took the  first of the  two posts. In 1773 his son, Charles-Pierre-Paul Savalette  de Langes  became his assistant and designated heir. In November 1785  they switched  positions, Langes becoming the titulary of the post and  Magnanville his  assistant and designated heir. Both men were maîtres des requêtes and conseillers d’Etat. The father was for a time intendant of Tours. The family could claim three degrees of nobility and thus came close, in principle, to the gentilhommerie.2 
One of the most active and influential Masons of his time,  Savalette  de Langes was first initiated in 1766 at the Lodge “L’Union  Indivisible”  in Lille, he was the founder of the Paris Lodge “
Les Amis Réunis” (1771), 
Regime of the Philalèthes   (1773), and convoked the Philalèthes Convents of Paris in 1785 and   1787. From the beginning Savalette was on the side of the Duke de   Chartres (future Duke d’Orléans) for the creation of the Grand Orient,   and after this was accomplished (1773) Savalette subsequently became its   Grand Officer and Archivist. He was also a member of the Paris Lodge   “L’Olympique de la Parfaite Estime” from 1783-88, the founder of “La   Société Olympique” in 1785, and a member of the Paris Lodge “Centre des   Amis” in 1793.

Permanent, official correspondence between the Illuminati and   Savalette’s Amis Réunis was established in 1784. Friedrich Wilhelm   Ludwig von Beulwitz (1755-1829), the head of the Rudolstadt Illuminati   was initiated into the Amis Réunis in 1784, while visiting Paris, and   received into the 11th class of the Philalèthes. Another Illuminatus,   Sigismund Falgera (1752-1790) was already initiated into the Amis Réunis   in 1784 (to 1789) and was appointed the official Illuminati   correspondent/liaison to the Paris Lodge.
4    Yet even before this, other Illuminati were simultaneously members of   the Amis Réunis – Count Kolowrat, for one (see below) – and it would  be  hard to believe that they hadn’t at least tried to “Illuminize” this   most important Lodge in Paris. In this regard, about all we can safely   say is that there remains a lack of documentation about any successes   the Illuminati may have had in France 
before 1787.
The famous trip Johann Joachim Christoph Bode (then head of the   Illuminati) had made from Weimar to Paris in 1787 has been for over 200   years a source of speculation. It turns out, however, that Bode had  kept  a travel journal that was only recently rediscovered and published  for  the first time in 1994. This, along with a letter Bode sent to   Illuminatus Christian, Prince of Hessen-Darmstadt (1763-1830) at   precisely the same time, includes the explicit admission that the Master   of the Amis Réunis and the Philalèthes, Savalette de Langes, after  over  a month of meetings and talks with Bode, was persuaded to join the   Illuminati. He was initiated on August 1st, 1787, followed three days   later by Jean-Baptiste-Marie-Adéodat Taillepied de Bondy (1741-1822)  and  Alexandre-Louis Roëttiers de Montaleau (1748-1808). This hitherto   unknown secret Lodge of the Illuminati in Paris had decided to operate   under another name – 
Philadelphes. Little else is known save   the pledge to work toward the “healthy reason” of the politically   inclined Illuminati. Additional Amis Réunis recruits during Bode’s visit   were Jean-Baptiste Le Sage (1757/67-1838) and Francois-Antoine Lemoyne   Daubermesnil (1748-1802).

In the letter to Christian von Darmstadt, Bode outlined some specifics about how the Illuminati would operate in France:
-  Correspondences should be marked with a cross. In this way, out  of  politeness and respect, rejections from the censors would be few;
 
-  The utilization of a standard Masonic cipher, but for the ninth  key,  the word St. … [a gap in the text, perhaps deliberately] from an  agreed  upon almanac;
 
-  Adopt the name Philadelphes instead of Illuminati, and in place of   Minervals, Preparatory class or Aspirants. One of the reasons, Bode   says, is that the Amis Réunis already have the class of Philalèthes for   their final grade. And finally, for those adverse to mysterious   societies, a beneficial assembly under the name Philanthropes.
 
Less than a year after Bode’s visit an organizational  transformation  did in fact take place at the Amis Réunis: a new Chapter  was instituted,  which included only one-fifth of the total number of  Amis Réunis  members. There were seventy-six members, according to  Hermann Schüttler,  of which eleven were known Illuminati. Of the  eleven, however, he only  lists ten: Daubermesnil, Le Sage, Roëttiers de  Montaleau, Savalette de  Langes, Taillepied de Bondy, Ludwig X.  Landgrave von Hessen-Darmstadt  (1753-1830), Friedrich Rudolf Salzmann  (1749-1820), Friedrich Tiemann  (1743-1802) and Russian envoy Count 
Alexander Sergeyevich Stroganov   (1733-1811). Among others, those who also belonged to the Chapter were   the banker brothers Louis-Daniel Tassin (1742-1794) and Gabriel Tassin   de l’Étang (1743-1794), Jean-Pierre Louis de Beyerlé (1740-1806) and   François-Marie Marquis de Chefdebien d’Armissan (1753-1814). Schüttler   rightly described it as a “lodge within a lodge within a lodge” (Amis   Réunis -> Illuminati/Philadelphes -> the new 1788 Chapter). About   the nature of its work nothing is known, only that it lasted until 1792   and had dwindled to 22 members.

The significance of this and other evidence, as it relates to the   conspiracy thesis of the French Revolution, is summarized by Porset:
The register of the Amis Réunis to which I have already referred, specifies, in 1789, which Brothers called for the recommencement of the Convent   of Paris on the occasion of the reunion of the   Estates-General…Montmorency-Luxembourg, who fled to England on the first   day of the Revolution, was a member of the Philalèthes, but he was not a revolutionary. Yet in a very interesting letter written at that time, to Chataigner, he blames the Philalèthes   and explains that he never wanted to give in to their pressure, but he   adds that he didn’t want to betray them - whom he respected; and   finally, Chaillon de Jonville, deputy Grand Master of the Grand Lodge,   thus the institution which preceded the Grand Orient, denounced the Philadelphes   in a text which appeared in 1789; he held them responsible for the   revolutionary disturbances. What more can be said? These Brothers of the   foremost Lodges, weren’t they in a position to speak [candidly] about   what they had experienced?7 
Professor Porset, himself a Grand Orient Mason, thus ends  his erudite  work on the Philalèthes by reluctantly admitting that the  18th Century  contemporary “anti-masonic” Illuminati conspiracy  theorists, such 
as Barruel, 
Starck, 
Lefranc, and 
Hervás y Panduro (though Robison might be mentioned in this company as well) were better-informed than has previously been suspected.

Another thing to keep in mind is that the Mesmerists in France at the   time, of which Savalette de Langes was an adherent, member, and   associate, were far from being harmless mystics. The formidable   historian, Robert Darnton has shown conclusively that the clubs and   Lodges of the Mesmerists, before, during, and after the Revolution, were   the premiere gathering places for revolutionaries and radical   pamphleteers.
9  As Porset has summarized:
…it suffices to remark that Mirabeau, Lafayette, Duport,   Brissot, Carra, Bergasse, the Rolands, d’Epremesnil, Desmoulins, Danton,   Robespierre, and Savalette de Langes, were all Masons and frequented   the same milieu, – and that this milieu, the Masonic-Mesmerists and   Illuminists, played a decisive role before and during the Revolution.
