Friedrich Melchior, Baron von Grimm
Friedrich Melchior, Baron von Grimm (26 December 1723 – 19 December 1807) was a German-born French-language journalist, art critic, diplomat and contributor to the Encyclopédie ou Dictionnaire raisonné des sciences, des arts et des métiers. In 1765 Grimm wrote Poème lyrique, an influential article for the Encyclopédie on lyric and opera librettos. Like Christoph Willibald Gluck Grimm became interested in opera reform. According to Martin Fontius, a German literary theorist, "sooner or later a book entitled The Aestatic ideas of Grimm will have to be written.
Grimm was born at Regensburg, the son of a pastor. He studied at the University of Leipzig, where he came under the influence of Johann Christian Gottsched and of Johann August Ernesti, to whom he was largely indebted for his critical appreciation of classical literature. When nineteen he produced a tragedy, Banise, which met with some success. After two years of study literature and philosophy he returned to home town, where he was attached to the household of Count Schönborn. In 1749 he accompanied his pupil, the young Schönborn, to Paris. There August Heinrich, Count Friesen appointed him as his secretary. Rousseau wrote in his Confessions Grimm played a cembalo and acted also as reader to the eldest son of Frederick, the young hereditary prince of Saxe-Gotha.
His acquaintance with Rousseau soon ripened into intimate friendship, through a mutual sympathy in regard to music and theater, and led to a close association with the encyclopaedists, like Diderot, Baron d'Holbach, d'Alembert, Marmontel, Morellet and Helvétius, who were meeting at Marie-Charlotte Hippolyte de Campet de Saujon. He rapidly obtained a thorough knowledge of the French language, and acquired so perfectly the tone and sentiments of the society in which he moved that all marks of his foreign origin and training seemed effaced. In 1750 he started to write for the Mercure de France on German literature and the ideas of Gottsched. In 1752, at the beginning of the Querelle des Bouffons, he wrote Lettre de M. Grimm sur Omphale. Grimm complained that the text of the libretto had no connection with the music. Grimm and Rousseau became the enemy of Élie Catherine Fréron. A witty pamphlet entitled Le Petit Prophète de Boehmischbroda (1753), "a parable about a Bohemian boy being sent to Paris to see the lamentable state into which the French opera has descended". This defence of Italian opera established his literary reputation. It is possible that the origin of the pamphlet is partly to be accounted for by his vehement passion for Marie Fel, the prima donna of the Paris Opera, who was one of the few French singers capable of performing Italian arias. When she refused him (and stayed in relation with Louis de Cahusac) Grimm fell into lethargy. Rousseau and abbé Raynal took care of him.
In 1753 Grimm, following the example of the abbé Raynal, and with Raynal's encouragement, began a literary newsletter with various German sovereigns. The first number of the Correspondance littéraire, philosophique et critique was dated May 15, 1753. With the aid of friends, especially of Diderot and Mme d'Épinay, who reviewed many plays, always anonymously, during his temporary absences from France, Grimm himself carried on the Correspondance littéraire, which consisted of two letters a month that were painstakingly copied in manuscript by amanuenses safely apart from the French censor in Zweibrücken, just over the border in the Palatinate.
Eventually Grimm counted among his 16 (or 25) subscribers: Princess Luise Dorothea of Saxe-Meiningen, Landgravine Caroline Louise of Hesse-Darmstadt, Louisa Ulrika of Prussia, Henry of Prussia, Catherine II of Russia, Leopold II, Holy Roman Emperor, Gustav III of Sweden, and many princes of the smaller German states, as Charles Frederick, Grand Duke of Baden, Karl August, Grand Duke of Saxe-Weimar-Eisenach, Charles Alexander, Margrave of Brandenburg-Ansbach, William Henry, Prince of Nassau-Saarbrücken, and Frederick Michael, Count Palatine of Zweibrücken. Between 1763 and 1766 Grimm attempted to recruit Frederick the Great as a subscriber. Mme Geoffrin, whose Parisian salon Grimm frequented, enrolled Stanislas Poniatowski as a subscriber, writing him "Here is your first number, together with Grimm's accompanying letter. Your Majesty will see that it is important that no copies be made. The German courts are very loyal to Grimm in this particular. I may even say to Your Majesty that negligence on this point could have serious consequences for me, the matter having passed through my hands."
The correspondence of Grimm was strictly confidential, and was not divulged during his lifetime. It embraces nearly the whole period from 1750 to 1790, but the later volumes, 1773 to 1790, were chiefly the work of his secretary, the Swiss Jakob Heinrich Meister, with whom he made acquaintance in the salon of Suzanne Curchod, the wife of Jacques Necker. At first he contented himself with enumerating the chief current views in literature and art and indicating very slightly the contents of the principal new books, but gradually his criticisms became more extended and trenchant, and he touched on nearly every subject — political, literary, artistic, social and religious — that interested the Parisian society of the time. His notices of contemporaries are somewhat severe, and he exhibits the foibles and selfishness of the society in which he moved; but he was unbiased in his literary judgments, and time has only served to confirm his criticisms. In style and manner of expression he is thoroughly French. He is generally somewhat cold in his appreciation, but his literary taste is delicate and subtle; and it was the opinion of Sainte-Beuve that the quality of his thought in his best moments will compare not unfavourably even with that of Voltaire. His religious and philosophical opinions were entirely skeptical.
Content of the Correspondance
For several years Grimm reported on the painters and paintings in the Salon de Paris, and was successfully succeeded by Diderot; he appreciated the architects Jacques-Germain Soufflot, and Claude-Nicolas Ledoux, the zoologist Buffon, the mathematician Leonhard Euler, and the political scientist Condorcet. Grimm asked Diderot to review "A Voyage Around the World" by Louis Antoine de Bougainville. Grimm had paid attention to the case Jean Calas, the problems between Rousseau and David Hume, the Montgolfier brothers, and Madame de Staël when she published her Letters on the works and character of J.J. Rousseau. The Correspondance became one of the influential media to spread malicious and false information on Rousseau.
Grimm did not appreciate Mondonville's Daphnis et Alcimadure, though he approved the use of the Occitan language, as being closer to Italian; according to Grimm "In Zoroastre it is day and night alternately; but as the poet...cannot count up to five he has got so muddled in his reckoning that he has been compelled to make it be day and night two or three times in each act, so that it might be day at the end of the play". He wrote about Caffarelli; about Pierre de Beaumarchais. Grimm didn't think much of Antoine de Léris. "The author claims that the public received his work with indulgence. If perfect oblivion may so be called, the author is right to be grateful"; The diminished Correspondance continued without Grimm until the revolutionary year 1790.
In 1755, after the death of Count Friesen, who was a nephew of Marshal Saxe and an officer in the French army, Grimm secured a sinecure worth 2000 livres a year as secretaire des commandements to Marshal d'Estrées on the Westphalia campaign of 1756–57 during Seven Years' War. He was named envoy of the town of Frankfort at the French court in 1759, but was deprived of his office for criticizing the comte de Broglie in a dispatch intercepted by Louis XV.
In 1751, Grimm was introduced by Rousseau to Madame d'Épinay, with whom he formed a liaison two years later, which led after four years to an irreconcilable rupture between him, Diderot and Rousseau. For thirty years Grimm was her lover.
Grimm and d'Holbach supported financially the mother of Thérèse Levasseur. Instead of Rousseau Grimm accompanied Mdm d'Épinay to Geneva to visit doctor Théodore Tronchin. Rousseau believed Grimm had made her pregnant.
Grimm criticized Rousseau's Julie, or the New Heloise and Emile, or On Education. Rousseau was induced by his resentment to give in his Confessions a malicious portrait of Grimm's character. Grimm's betrayals of his closest friend, Diderot, finally led Diderot to bitter denunciations of him too in his "Lettre apologétique de l'abbé Raynal à M. Grimm" in 1781. In 1783, he lost his most intimate friend, Mme d'Épinay, and in the following year Diderot.
Not long after he showed Prince Henry of Prussia, on a diplomatic trip, around in Paris.
Mozart's three visits to Paris
Leopold Mozart decided to take his two child prodigies, the boy, Wolfgang (born January 27, 1756), then aged 7, and the girl, Nannerl (Maria Anna, born July 30, 1751), then aged 12, on their "Grand Tour" in June 1763. Mozart's first visit to Paris lasted from November 18, 1763 to April 10, 1764, when they departed for London. All the many letters of recommendation carried by Leopold proved ineffectual, except the one to Melchior Grimm, which led to an effective connection. Grimm was a German who had moved to Paris at age 25, and was an advanced amateur of music and opera, which he covered as a Paris-based journalist for the aristocracy of Europe. He was persuaded "to take the German prodigies under his wing." Grimm published a highly supportive article on the Mozart children in his Correspondance Littéraire of December 1763, to facilitate Leopold's entrée into Parisian high society and musical circles.
The son of Grimm's employer, Louis Philippe II, helped the Mozarts perform in Versailles, where they stayed for two weeks over Christmas and New Year.  Abert explains that "only when they had performed at Versailles were they admitted to, and admired by, aristocratic circles." Grimm recounted with pride the impressive improvisations produced by young Mozart in private and public concerts. Leopold had four of his sonatas for keyboard and violin engraved and dedicated to the King's daughter, Princess Victoire, and the Dauphine's lady-in-waiting, by "THEOPH:W:MOZART Compositeur, et Maitre de Musique, agé de 7 ans". Carmontelle produced a group portrait of the family at play, engraved at Grimm's instigation. Ollivier painted Wolfgang playing the keyboard in the Prince of Conti's salon, a painting now in the Louvre Museum.
After their long stay in London (15 months) and Holland (8 months), the Mozarts closed their "Grand Tour", which lasted three years and a half, by stopping over in Paris for Mozart's second visit to the French capital, May 10 - July 9, 1766. Again, they were helped, guided, and mentored by Grimm. The children were by then 10 and 15, and had lost some of their public appeal as young prodigies on the now somewhat blasé Parisians. Grimm wrote a very flattering letter about the Mozart children dated 15 July 1766 in his Correspondance Littéraire. Commenting on Mozart's remarkable progress in all areas of music-making, Grimm predicted the future operatic success of the young composer: "He has even written several Italian arias, and I have little doubt that before he has reached the age of twelve, he will already have had an opera performed at some Italian theatre."
However Hermann Abert warns that the reason why Grimm's Journal "nonetheless needs to be treated with caution is due to the personality of its principal contributor, for Grimm was not sufficiently well trained as a musician to do justice to the art that he was describing, nor was he the man to let slip the opportunity for a flash of wit or eloquent turn of phrase, even if it meant violating the truth in the process." Grimm's second prediction at the end of the same letter didn't turn out as prescient as the first one: "If these children live, they will not remain at Salzburg. Before long monarchs will vie for their possession." In fact, Mozart was unable to obtain employment as an opera composer from a European court and remained a free-lance opera writer all his life.
Leopold sent Mozart, then aged 22, to Paris for his third and last visit, from March 23d to September 26, 1778. But this time Mozart was alone with his mother, Anna Maria Mozart, while Leopold stayed back in Salzburg, in order to save his employment. Grimm helped, guided, and advised Mozart and his mother again, acting as a proud manager. But Mozart mostly encountered a series of disappointments, while tragedy struck when Anna Maria fell sick, due to her loneliness, poor living conditions, and poor food. She was duly bled, and died on July 3, 1778. After which, Mozart stayed with Grimm, who, as personal secretary of the Duke of Orleans, lived in the ducal mansion. For the first time in his life, Mozart was on his own.
Grimm, a man with strong opinions, nicknamed "Tyrant le Blanc", and Mozart did not get along very well. Mozart found himself extremely unhappy in Paris. The city was "indescribably dirty"; Grimm complained he was "not running around enough" to get pupils, as he found that calling on his introductions was tiring, too expensive, and unproductive: "People pay their respects, and that's it. They arrange for me to come on such and such a day; I then play for them, and they say 'Oh, c'est un prodige, c'est inconcevable, c'est étonnant.' And, with that, adieu." He never got paid for his Concerto for flute and harp in C K 299, written for the Duke of Guines and his daughter, nor for his ballet Les Petits Riens K. 299b.
Mozart was recruited by the director of the "Concert Spirituel", Joseph Legros, to write some choruses, K. 297a, which were played without giving credit to Mozart. Then Mozart wrote a Sinfonia concertante in E flat major K. 297b, for a group of four wind players from Mannheim, which he sold to Legros without keeping a copy. Legros never had it copied for performance, and the work became considered "lost". Mozart at last enjoyed one great success at the Concert Spirituel as a composer with his Symphony No. 31 in D, K. 297 (Paris Symphony), performed on June 18, 1778 "to unanimous acclaim".
Mozart kept finding Paris "totally at odds" with his "genius, inclinations, knowledge, and sympathies". He kept expressing his deep dislike of the French, their character, their rudeness, their being "frightfully arrogant", and he was "appalled by their general immorality". Like Jean-Jacques Rousseau, Mozart found the French language inherently unmusical and "so damned impossible where music is concerned", ironizing that "the devil himself must have invented the language of these people". He felt that French music was worthless: "They understand nothing about music", echoing what Leopold had declared during their first visit to Paris: "The whole of French music is not worth a sou". He judged their singers inept. "I'm surrounded by nothing but beasts and animals. But how can it be otherwise, for they're just the same in all their actions, emotions, and passions." 
Suspicious by nature, Mozart ended up distrusting Grimm, while "Grimm himself was bound to find Mozart increasingly baffling as a person — with his curious mixture of self-confidence and dreaminess". Mozart found himself obliged to borrow "as much as fifteen louis d'or" from Grimm. Voltaire's death on May 30, 1778 made clear "the full extent of the yawning void between them". Grimm warned Leopold that the need for continual and intense networking in Paris was too demanding for Wolfgang, "for it is a very tiring thing to run to the four corners of Paris and exhaust oneself in explanations. And then this profession will not please him, because it will keep him from writing, which is what he likes above all things."  Their dealings "ended on a note of the deepest disharmony." Leopold agreed that Mozart should leave Paris: "You don't like Paris, and on the whole I don't blame you...My next letter will tell you that you are to leave Paris." Grimm organized for Mozart's trip to Strasbourg, promising a diligence to cover the trip in five days, but forced Mozart to travel by stagecoach, a journey that took twelve days. Mozart "himself left the city on September 26, as ill-tempered and disgruntled as when he had arrived there." Mozart broke the journey in Nancy on Oct. 3, finally arriving in Strasbourg on Oct. 14, 1778.
In the course of his three visits, Mozart spent a total of 13 months in Paris, all of them under the guidance and assistance of Grimm.
Catherine II of Russia
His introduction to Catherine II of Russia took place at Saint Petersburg in 1773, when he was in the suite of Wilhelmina of Hesse-Darmstadt on the occasion of her marriage to the Tsarevitch Paul. A few weeks later Diderot arrived. On 1 November they both became members of the Russian Academy of Sciences. Because of his atheism Diderot hat little success in the imperial capital. When Diderot criticized Catharina's style of governing, Grimm moved away from him. According Jonathan Israel Grimm was a representative of the Enlightened Absolutism. Grimm introduced Ferdinando Galiani and Cesare Beccaria and promoted Jean Huber and Johann Friedrich Reiffenstein in the Russian Empire.
He became minister of Saxe-Gotha at the French court in 1776. In 1777 he again visited to Saint Petersburg, where he remained for nearly a year. Grimm loved to play chess and cards with the empress. According to Simon Dixon he influenced Catharina with his ideas on Rousseau. He acted as Paris agent for the empress in the purchase of works of art, and executed many confidential commissions for her. With his help the libraries of Diderot (in 1766) and Voltaire (in 1778) were bought and sent to the Russian capital. In 1779 Grimm introduced Giacomo Quarenghi as architect and Clodion as sculptor, when Étienne Maurice Falconet came back to Paris. In 1787, Catherina asked Grimm to burn her letters to him, "or else put them in save keeping, so no one can unreveal them for a century."
Chevalier de Saint-Georges
Like Christoph Willibald von Gluck and Ranieri de’ Calzabigi Grimm was occupied with operatic reform. Grimm loved theater, criticized the Comédie Française and praised the private theater of Madame de Montesson, the wife of his employer. In 1776, the Académie royale de musique, the (Paris Opéra), was once again in dire straits. A "consortium of capitalists", to quote the critic Baron Grimm, proposed Chevalier de Saint-Georges as the next director of the opera. He helped Saint-Georges, living in the adjacent mansion with Madame de Montesson. Mozart spent over two months next to Saint-Georges. The two mansions had a communal garden, a chapel and a theater.
From "Erinnerungen einer Urgrossmutter" it becomes clear he left Rue de Mont Blanc in 1792, and settled in Gotha, living in the ducal palace Friedenstein Castle. His poverty was relieved by Catherine, who shortly before her death appointed him minister of Russia at Hamburg. Although not very exited, he traveled with Émilie de Belsunce, Mme d'Épinay's granddaughter, later comtesse de Bueil. Grimm gave up his new post when he suddenly became blind on 17 January 1797. (Grimm had problems with his eyesight since 1762.) Grimm and the young Émily stayed a few weeks in Altona. They travelled to Braunschweig and stayed there Summer 1797 until June 1800. There Émilie was educated by Willem Bilderdijk. Then he was reinvited by Ernest II, Duke of Saxe-Gotha-Altenburg. He died at Gotha on 19 December 1807.
The main-belt asteroid 6912 Grimm was named after him.
Grimm's Correspondance littéraire, philosophique et critique ..., depuis 1753 jusqu'en 1769, was edited, with many excisions, by Jean-Baptiste-Antoine Suard and published at Paris in 1812, in 6 vols. 8vo; deuxième partie, de 1771 a 1782, in 1812 in 5 vols. 8vo; and troisième partie, pendant une partie des années 1775 et 1776, et pendant les années 1782 a 1790 inclusivement, in 1813 in 5 vols. 8vo. A supplementary volume appeared in 1814; the whole correspondence was collected and published by Jules-Antoine Taschereau, with the assistance of A. Chaudé, in a Nouvelle Édition, revue et mise dans un meilleur ordre, avec des notes et des éclaircissements, et oil se trouvent rétablies pour la première fois les phrases supprimées par la censure impériale (Paris, 1829, 15 vols. 8vo); and the Correspondance inédite, et recueil de lettres, poésies, morceaux, et fragments retranchés par la censure impériale en 1812 et 1813 was published in 1829. The standard edition is that of Jean Maurice Tourneux (16 vols., 1877–1882). It is now being replaced by the new edition published by Ulla Kölving at the Centre international d'étude du XVIIIe siècle, Ferney-Voltaire.
Grimm's Mémoire Historique sur l'origine et les suites de mon attachement pour l'impératrice Catherine II jusqu'au décès de sa majesté impériale, and Catherine's correspondence with Grimm (1774–1796) were published by J. Grot in 1880, in the collection of the Russian Imperial Historical Society. She treats him very familiarly, and calls him Heraclite, Georges Dandin, etc. At the time of the Revolution she begged him to destroy her letters, but he refused, and after his death they were returned to Saint Petersburg. Grimm's side of the correspondence, however, is only partially preserved. He signs himself "Pleureur". Some of Grimm's letters, besides the official correspondence, are included in the edition of Tourneux; others are contained in the Erinnerungen einer Urgrossmutter of Katharina von Bechtolsheim, edited (Berlin, 1902) by Count C. Oberndorff.
