Early fiction Voltaire's next play,
Artémire, set in ancient Macedonia, opened on 15 February 1720. It was a flop and only fragments of the text survive. He instead turned to an epic poem about
Henry IV of France that he had begun in early 1717. Denied a licence to publish, in August 1722 Voltaire headed north to find a publisher outside France. On the journey, he was accompanied by his mistress, Marie-Marguerite de Rupelmonde, a young widow. At Brussels, Voltaire and Rousseau met up for a few days, before Voltaire and his mistress continued northwards. A publisher was eventually secured in The Hague. In the Netherlands, Voltaire was struck and impressed by the openness and tolerance of Dutch society. On his return to France, he secured a second publisher in
Rouen, who agreed to publish
La Henriade clandestinely. After Voltaire's recovery from a month-long
smallpox infection in November 1723, the first copies were smuggled into Paris and distributed. While the poem was an instant success, Voltaire's new play,
Mariamne, was a failure when it first opened in March 1724. Heavily reworked, it opened at the
Comédie-Française in April 1725 to a much-improved reception. It was among the entertainments provided at the wedding of
Louis XV and
Marie Leszczyńska in September 1725.
Exile in England In early 1726,
Guy Auguste de Rohan-Chabot taunted Voltaire about his name change, who retorted that his name would win the esteem of the world, while Rohan would sully his own. A furious Rohan arranged for his servants to beat Voltaire a few days later. Seeking redress, Voltaire challenged Rohan to a duel, but the powerful Rohan family arranged for Voltaire to be arrested and imprisoned without trial in the Bastille on 17 April 1726. Fearing indefinite imprisonment, Voltaire asked to be exiled to England as an alternative punishment, which the French authorities accepted. On 2 May, he was escorted from the Bastille to
Calais and embarked for England. In England, Voltaire lived largely in
Wandsworth, with acquaintances including
Everard Fawkener, an English merchant whom he had met in Paris. In late 1726, he lived for a year in rented rooms on Durham Court, near today's John Adam Street, south of the Strand, in a house belonging to the former secretary of
Lord Bolingbroke, which gave Voltaire an ideal location in the centre of the capital. From December 1727 to June 1728 he lodged above The White Peruke, a French barber/wig maker shop at 10 Maiden Lane,
Covent Garden, now commemorated by a green plaque, to be nearer to his British publisher, Peter Vaillant, a
Huguenot printer and bookseller. The Huguenot printing community located in this area had numerous French émigrés and a French church at the Savoy, making Voltaire feel at home. Voltaire took on a
Quaker, Edward Higginson, as an English tutor. Voltaire's affinity for and familiarity with the Quakers was a major factor in the development of the stock figure of the "Good Quaker" as a paragon of virtue in the literature of the French Enlightenment. Voltaire circulated throughout English high society, meeting
Alexander Pope,
John Gay,
Jonathan Swift,
Lady Mary Wortley Montagu,
Sarah, Duchess of Marlborough, and many other members of the nobility and royalty. Voltaire's exile in England greatly influenced his thinking. He was intrigued by Britain's
constitutional monarchy in contrast to French
absolutism and by the country's greater freedom of speech and religion. He was influenced by the writers of the time and developed an interest in English literature, especially
Shakespeare, who was still little known in continental Europe. Despite pointing out Shakespeare's deviations from neoclassical standards, Voltaire saw him as an example for French drama, which, though more polished, lacked on-stage action. Later, as Shakespeare's influence began growing in France, Voltaire tried to set a contrary example with his own plays, decrying what he considered Shakespeare's barbarities. Voltaire may have been present at the funeral of
Isaac Newton and met Newton's niece
Catherine Conduitt. In 1727, Voltaire published two essays in English,
Upon the Civil Wars of France, Extracted from Curious Manuscripts and
Upon Epic Poetry of the European Nations, from Homer Down to Milton. He also published a letter about the Quakers after attending one of their services. After two and a half years in exile, Voltaire returned to France, and after a few months in
Dieppe, the authorities permitted him to return to Paris. At a dinner, French mathematician
Charles Marie de La Condamine proposed buying up the lottery that was organized by the French government to pay off its debts, and Voltaire joined the consortium, earning perhaps a million
livres. He invested the money cleverly and on this basis managed to convince the
Court of Finances of his responsible conduct, allowing him to take control of a trust fund inherited from his father. He was now indisputably rich. Further success followed in 1732 with his play
Zaïre, which when published in 1733 carried a dedication to Fawkener praising English liberty and commerce. He published his admiring essays on British government, literature, religion, and science in
Letters Concerning the English Nation (London, 1733). In 1734, they were published in Rouen as
Lettres philosophiques, causing a huge scandal. Published without approval of the royal censor, the essays lauded British constitutional monarchy as more developed and more respectful of human rights than its French counterpart, particularly regarding religious tolerance. The book was
publicly burnt and banned, and Voltaire was again forced to flee Paris.
Château de Cirey appears as Voltaire's muse, reflecting Newton's heavenly insights down to Voltaire. In 1733, Voltaire met
Émilie du Châtelet (Marquise du Châtelet), a mathematician and married mother of three, who was 12 years his junior and with whom he was to have an affair for 16 years. To avoid arrest after the publication of
Lettres philosophiques, Voltaire took refuge at her husband's château at
Cirey on the borders of
Champagne and
Lorraine. Voltaire paid for the building's renovation, and Émilie's husband sometimes stayed at the château with his wife and her lover. The intellectual paramours collected around 21,000 books, an enormous number for the time. Together, they studied these books and performed scientific experiments at Cirey, including an attempt to determine the nature of fire. Having learned from his previous brushes with the authorities, Voltaire began his habit of avoiding open confrontation with the authorities and denying any awkward responsibility. He continued to write plays, such as
Mérope (or
La Mérope française) and began his long researches into science and history. Again, a main source of inspiration for Voltaire were the years of his British exile, during which he had been strongly influenced by Newton's works. Voltaire strongly believed in Newton's theories; he performed experiments in
optics at Cirey, and was one of the promulgators of the famous story of Newton's inspiration from the falling apple, which he had learned from Newton's niece in London and first mentioned in his
Letters. , 1735 In the fall of 1735, Voltaire was visited by
Francesco Algarotti, who was preparing a book about Newton in Italian. Partly inspired by the visit, the Marquise translated Newton's Latin
Principia into French, which remained the definitive French version into the 21st century. Voltaire and the Marquise also studied history, particularly the great contributors to civilization. Voltaire's second essay in English had been "Essay upon the Civil Wars in France". It was followed by
La Henriade, an epic poem on the French
King Henri IV, glorifying his attempt to end the Catholic-Protestant massacres with the
Edict of Nantes, which established religious toleration. There followed a historical novel on King
Charles XII of Sweden. These, along with his
Letters on the English, mark the beginning of Voltaire's open criticism of intolerance and established religions. Voltaire and the Marquise also explored philosophy, particularly
metaphysical questions concerning the existence of God and the soul. Voltaire and the Marquise analyzed the Bible and concluded that much of its content was dubious. Voltaire's critical views on religion led to his belief in
separation of church and state and religious freedom, ideas that he had formed after his stay in England. In August 1736,
Frederick the Great, then Crown Prince of
Prussia and a great admirer of Voltaire, initiated a correspondence with him. That December, Voltaire moved to
Holland for two months and became acquainted with the scientists
Herman Boerhaave and
Willem 's Gravesande. From mid-1739 to mid-1740 Voltaire lived largely in Brussels, at first with the Marquise, who was unsuccessfully attempting to pursue a 60-year-old family legal case regarding the ownership of two estates in
Limburg. In July 1740, he traveled to the Hague on behalf of Frederick in an attempt to dissuade a dubious publisher, van Duren, from printing without permission Frederick's
Anti-Machiavel. In September Voltaire and Frederick (now King) met for the first time in
Moyland Castle near
Cleves and in November Voltaire was Frederick's guest in Berlin for two weeks, followed by a meeting in September 1742 at
Aix-la-Chapelle. Voltaire was sent to Frederick's court in 1743 by the French government as an envoy and spy to gauge Frederick's military intentions in the
War of the Austrian Succession. Though deeply committed to the Marquise, Voltaire by 1744 found life at her château confining. On a visit to Paris that year, he found a new love—his niece. At first, his attraction to
Marie Louise Mignot was clearly sexual, as evidenced by his letters to her (only discovered in 1957). Much later, they lived together, perhaps platonically, and remained together until Voltaire's death. Meanwhile, the Marquise also took a lover, the
Marquis de Saint-Lambert.
Prussia : guests of Frederick the Great at
Sanssouci, including members of the
Prussian Academy of Sciences and Voltaire, third from left After the death of the Marquise in childbirth in September 1749, Voltaire briefly returned to Paris and in mid-1750 moved to
Potsdam, Prussia, at the invitation of Frederick the Great. The Prussian king (with the permission of Louis XV) made him a chamberlain in his household, appointed him to the
Order of Merit, and gave him a salary of 20,000
French livres a year. He had rooms at
Sanssouci and
Charlottenburg Palace. Life went well for Voltaire at first, and in 1751 he completed
Micromégas, a piece of science fiction involving ambassadors from another planet witnessing the follies of humankind. However, his relationship with Frederick began to deteriorate after he was accused of theft and forgery by a Jewish financier, Abraham Hirschel, who had invested in Saxon government bonds on behalf of Voltaire at a time when Frederick was involved in sensitive diplomatic negotiations with
Saxony. He encountered other difficulties: an argument with
Maupertuis, the president of the
Berlin Academy of Science and a former rival for Émilie's affections, provoked Voltaire's
Diatribe du docteur Akakia ("Diatribe of Doctor Akakia"), which satirized some of Maupertuis's theories and his persecutions of a mutual acquaintance,
Johann Samuel König. This greatly angered Frederick, who ordered all copies of the document burned. On 1 January 1752, Voltaire offered to resign as chamberlain and return his insignia of the Order of Merit; at first, Frederick refused until eventually permitting Voltaire to leave in March. On a slow journey back to France, Voltaire stayed at
Leipzig and
Gotha for a month each, and
Kassel for two weeks, arriving at
Frankfurt on 31 May. The following morning, he was detained at an inn by Frederick's agents, who held him in the city for over three weeks while Voltaire and Frederick argued by letter over the return of a satirical book of poetry Frederick had lent to Voltaire. Marie Louise joined him on 9 June. She and her uncle only left Frankfurt in July after she had defended herself from the unwanted advances of one of Frederick's agents, and Voltaire's luggage had been ransacked and valuable items taken. Voltaire's attempts to vilify Frederick for his agents' actions at Frankfurt were largely unsuccessful, including his
Mémoires pour Servir à la Vie de M. de Voltaire, published posthumously, in which he also explicitly made mention of Frederick's homosexuality, when he described how the king regularly invited pages, young cadets or lieutenants from his regiment to have coffee with him and then withdrew with the favourite for a quickie. However, the correspondence between them continued, and though they never met in person again, after the
Seven Years' War they largely reconciled.
Geneva and Ferney '' at
Ferney, France Voltaire's slow progress toward Paris continued through
Mainz,
Mannheim,
Strasbourg, and
Colmar, but in January 1754
Louis XV banned him from Paris, and he turned for
Geneva, near which he bought a large estate (
Les Délices) in early 1755. Though he was received openly at first, the law in Geneva, which banned theatrical performances, and the publication of
The Maid of Orleans against his will soured his relationship with Calvinist Genevans. In late 1758, he bought an even larger estate at
Ferney, on the French side of the
Franco-Swiss border. The town would adopt his name, calling itself Ferney-Voltaire, and this became its official name in 1878. Early in 1759, Voltaire completed and published ''
Candide, ou l'Optimisme (Candide, or Optimism''). This satire on Leibniz's philosophy of optimistic determinism remains Voltaire's best-known work. He would stay in Ferney for most of the remaining 20 years of his life, frequently entertaining distinguished guests, such as
James Boswell (who recorded their conversations in his journal and memoranda),
Adam Smith,
Giacomo Casanova, and
Edward Gibbon. In 1764, he published one of his best-known philosophical works, the
Dictionnaire philosophique, a series of articles mainly on Christian history and dogmas, a few of which were originally written in Berlin. However, Franklin was merely a visitor at the time Voltaire was initiated, the two only met a month before Voltaire's death, and their interactions with each other were brief. == Death and burial ==
